Powerflow Exhaust system
We all know that our Hilux are thirsty and the fuel price are just keep in rising. It is also general knowledge that a 2.7 Hilux is a bit sluggish on uphills, so I eventually decided to have a freeflow system installed.
I never wanted to do this before because the last thing I want is a noisy overlanding vehicle, it just don't go well with game viewing.
So I had a chat with Justin who is the owner of Powerflow Exhausts in Tokai, Cape Town. He told me not to worry, he will design me a system that will give me the better performance and better fuel consumption and still be as quiet as a normal vehicle.
So I took my Hilux there on Thursday. Again I stressed the point that if it is noisy I don't want it. Don't get me wrong, I just love the racy tone of an exhaust system on the right vehicle, but I want my Hilux to be quiet. One day when I build a V8 Hilux to play with I will have a proper system with the right tone installed, but not now.
First Justin took a piece of hose pipe and went through the front part of the exhaust system to check for leaks. From where the manifold bolts onto the head all the way to the first box.
He then announced that even after 430,000km the front portion of the system is as good as new. He told me that he is not going to fiddle with the front part. The original Toyota manifold is very well designed. The little bit of power you gain by fitting branches is not worth the money you spend. Then there is the famous Toyota "torque box" . He said that is one thing Toyota got right on these vehicles and you do not want to mess with or remove that torque box.
So even though he could easily have made an extra thousand bucks out of me, he advised that we leave the front part as it is. I appreciate his honesty, it shows me he does this because he wants the best for his client and not the best for his pocket.
This front part is still fine
This is the torque box they are talking about
I wanted them to change the flow of the pipe where it runs under the propshaft, but if you look on the side of the gearbox you will see that the spedo cable and handbrake cables run in the same area and putting the exhaust there will create new problems. Justin then said something I did not think about that way; "If you haven't buggered up that pipe in 430,000km it shows you that it is not really a problem"
So I decided to leave it as it is.
Justin appointed Russel Rogers to the job. This guy don't talk much and is really good in what he is doing.
He cut off the old pipe in front of the flange of the rear silencer
Then carefully put the new rear silencer in place where it will go
Bent the pipes to perfection
At first he tried to fit the small silencer under the load bin. I saw there was not much space there and then I called our Hilux specialist, Hoppy for his good advice (as usual). Hoppy said I must check, the box fits nicely on the outside of the chassis under the loadbin. So we run the pipe between the chassis and springs and put the silencer under the loadbin on the outside.
I did not do all the fancy dino testing stuff, but I can definitely feel an increase in performance, especially between 1500 and 300 rpm. No more sluggishness and it makes town driving much easier. So far I could not test the fuel consumption because on my way back to Langebaan I loaded some shelves on the canopy which had a lot of wind resistance and my next trip was to Hermanus with a trailer on. So only on my next tank will I be able to report on the fuel consumption.
As for the noise....... I think it is even quieter than the standard system used to be, so a big thumbs up for Just and Russel, they exceeded my expectations.
Powerflowcan build a system for ANY vehicle.
You can expect a performance gain of anywhere between 5 – 10% by fitting a POWERFLOWexhaust – some vehicles respond better than others
The price of the system was R2,500.00 which included everything, also a 5 year guarantee. That is the price for most "standard" 4x4 vehicles.
Apparently this price will differ if you have extra fuel tanks, a V6, or whatever you have which creates more work.
They can fit branches as well, although in my case they advised me not to, if they did the branches would have cost an extra R2,000.00
Best will be to call Justin (021 701 5513) to get a price.

Nice write up Peter. Thanks
I will need to have a system built soon.
Hopefully the Power Flow agency in Durban is as clued up

Re: Powerflow Exhaust system
Excellent post Pieter,
Was pondering the same conversion, and seeing that we have similiar mileage on our vehicles, your post was very relevant. My 2.7 Hilux has 490 000 on the clock, and I also experienced a sluggishness on uphills, and the diagnosis was that the mixture was very lean. A SAC chip only did solve that, but I was contemplating the free flow exhaust option as well.
Lets hope the Powerflow guys in Gauteng can benefit from this info too.
Cheers for that.
Peter

Re: Powerflow Exhaust system
My experience with PowerFlow is slightly different, however I'm also a very happy customer. I went to PowerFlow in Salt River.
I had the following issues. On my last trip to Botswana a hole formed on the downpipe, just after the manifold which I had to repair with Gungum, hose clamps and a Coke can. I also found that the bend of the standard exhaust, between the manifold and the torque box, was too low and often scraped on tough obstacles on grade 4 trails, eventually my exhaust bumped a rock and it snapped the weld right off the torque box. Time to visit PowerFlow.
The back half of my system, from the torque box all the way to the rear was already PowerFlow stainless system, with box and rear silencer, fitted by previous owner, which by the looks of it is basically what you fitted Piet.
I had had enough with my current exhaust issues so decided to replace everything, including the branch, for piece of mind. PowerFlow has a standard stock item, stainless Brospeed branch, which is designed specifically for the 2.7 Hilux which is simply a 'bolt-on'. Apparently unless Brospeed get greater than a certain % improvement in power and economy they don't bother manufacturing the branch.
I wanted the torque box removed because it was just another point of failure to break and scrape on rocks, looked rusted and PowerFlow advised me that it wasn't really necessary to replace.
I also wanted my stock manifold/branch replaced with stainless for peace of mind, in-case it was also rusting. I also wanted a full stainless steel system and not have to worry about rusting and holes anywhere in the system on my next overland trip.
Just comparing the standard manifold to the Brospeed branch you can see a huge difference in construction. The pipes on the Brospeed branch are much wider and longer (almost 1m long), literally only merging into a single pipe just before the bend right at the bottom. I'm no expert but just looking at the standard branch next to the Brospeed you can't help but feel that the Brospeed will allow better air-flow and took a lot of clever design work to get right.
The branch fits perfectly with no bending or modifications required. After they fitted the branch I got them to bend the new down-pipe right up close to the drive shaft, out the way of rocks and now my exhaust is far away from the lowest point of my bakkie and hasn't even taken the slightest scratch on the trails.
Power, consumption, torque have all definitely all improved. I haven't had my chip tuned again and therefore expect that if I did I could get even better results. When town driving and highway driving the system sounds quieter than the standard system, it just has a nicer, more resonant and deeper tone. However when you rev it to the limiter on a dune its comes alive and sounds awesome!
If I recall I paid about R750 for the branch and R750 for the pipe from the branch to the rear.

Re: Powerflow Exhaust system
Pieter,
You are going to curse the pipe out the side. I also had it and it made the walls, other peoples cars and anyone walking past dirty, especially when cold starting. I eventually turned it downwards.

Just because it says "4WD" doesn't make it an off-road vehicle.

My pipe points downwards too and isn't even visible, I think this also helps keep the noise down.

Re: Powerflow Exhaust system
Ek het my lux se stel 3 jaar terug met s/s freeflow vervang in Somersetwes by Wheel en Steel teen R2000, paar made later neem ek hom na PowerFlow Bellville vir die branch toe word ek gewys die manne van Somerset het 'n groot gemors aan gevang met die sogenaamde freeflow wat hul ingesit het.
Ja en daai "Then there is the famous Toyota "torque box" " die het die manne van Somersetwes uit gehaal en weg gegooi.
Die eienaar van Powerflow Bellville (kan nou nie meer sy naam onthou) sê toe daar is 'n sekere VW "torque box" wat sal werk ek moet gaan soek vir die. Die fitter wat toe gesê hul het so box en di is toe gratis in gesit saam met die nuwe regte stel.
Pieter ek was ook megedeel dat op die 2.7 los 'n ou die voorstedeel tensy hy reeds gekraak of beskadig is.
Ek was so tevrede dat ek my Golf ook na hul toe geneem het.

Re: Powerflow Exhaust system
I am sorry but the “torque box” idea is a load of horse manure in my opinion, and the experts agree. A silencer cannot create torque or change the torque curve. It can reduce the torque if it increases the back pressure but that is it, The torque spread is determined by the header or branch, effectively the configuration and the length of the primaries and secondary’s. The 4 into one which the standard 2.7 exhaust manifold basically is, is the least effective. The 4 into 2 into 1 is the most effective for best low down torque. I have played around with this quite a bit and what I did on my previous 2.7 was to simply keep the standard branch but at the first collector where the pipes merged from 4 into 1 I had them make a flange which extended the two secondary’s down to about level with the chassis where it merged into one. You the effectively have a 4 into 2 into 1 branch. The first collector is at the original flange the second collector is at chassis level where the final two merge into one. The dyno curve for the home made 4-2-1 branch was the same as an aftermarket 4-2-1 which I subsequently fitted. Have a look at the high revving race car type setups they will almost always have a 4 into 1 branch setup. Engines designed for low down torque will almost always have a 4 into 2 into in 1 configuration. No a 4 stroke engine does not need back pressure, that is exactly the opposite of what you are trying to achieve with a correctly designed exhaust system.

A quote form Abel Dos Santos the owner of Viper Performance Exhausts http://viperperformance.co.za
"Just keep in mind that all a silencer does is reduce noise. It does not make power. So the best silencer for maximum performance is NO SILENCER AT ALL!"

Re: Powerflow Exhaust system
Ai Willem if I knew that before I went there I could ask them to do that
But maybe it is good that I did not.
I think one day I will go there and ask for the front piece to be changed as you described.
When you did your 4-2-1 setup, did you still run it underneath the propshaft like the original system?

Re: Powerflow Exhaust system
Pieter yes I did, very difficlult to route it somewhere else. But as you also noted I have never damaged that part. I wanted to change the routing to keep the heat away from the front propshaft and the bend restricts the flow a bit. My previous 2.7 2x4 had a 63mm system because it did not have the front propshaft, the current one is a 57mm. The 63mm is a bit more difficult to bend in the tight spots.
Ek sal kyk of ek nog die gedeelte van die pyp by die huis het en 'n foto opsit as ek dit nog het.

When it idles for a while in the garage it make some marks on the wall, but it doesnt bother me at all since it is a place where I work on things.

Re: Powerflow Exhaust system
Very informative post 3RZ! Do you think its worth spending the money on having my bakkie tuned and dyno'ed now that I have fitted the Brospeed branch and removed the front box?

Re: Powerflow Exhaust system
Everyone is entitled to their own opinion.
The famous / infamous "torque box" has a baffled reducer in it - what we call a star squash - some of you might think that I am talking bollie but the 2.7 will "drive" better with it in if it still has the standard manifold and downpipe setup - once a branch is fitted this changes everything completely and the "torque" box can then be removed
When I say it "drives" better I am talking about every day driveability - especially in the bottom and middle of the rev range - how many 4X4 owners really "ry hom innie rooi" on a regular basis. Forget about what dyno's say but how your vehicle feels to you.
"If I recall I paid about R750 for the branch and R750 for the pipe from the branch to the rear" - No offence but i think you are mistaken - we sincerely wish the prices could be so low - a complete POWERFLOW exhaust system for a 2.7 is R2500 and the BROSPEED branch is R2200.
Please do not hesitate to call me at POWERFLOW TOKAI on 021 701 5513 or Dick at POWERFLOW SALT RIVER on 021 448 1325 or Roddy at POWERFLOW BELLVILLE on 021 930 7717 any time to discuss your specific needs - we wish we could answer every question in writing here on the forum but this is impossible from a time point of view

Re: Powerflow Exhaust system
A diesel engine obviously works very differently to a petrol engine BUT a POWERFLOW exhaust can definitely improve its performance.Longway wrote:Happy that it worked out.
Can anyone say what this new pipe will do for a disel 3.0 D4D
Thanks

Re: Powerflow Exhaust system
Justin you right there.
A few years ago I also removed my Sfa 2.2 std small box for some reason. Most of the low down torque was missing. Then between Carb settings, ignition, sparkplugs playing to get more power again, it was time for a new exhaust. I fitted std as per the guys told me with all the boxes, and the power was back.
Do not under estimate it.

Re: Powerflow Exhaust system
Justin THANKS for the feedback. As previously posted I have used Roddy's services a couple of times in the past, even refered a number of friends there. Service has always been EXCELLENT.
When you have the time - would you please give us a write up on how exhausts influence power on turbo diesels. (is there any use in fiddling with it to get some more SAFE power out of the engine?)
I have the 2,5 D-4D and will probably add an intercooler in the near future. At that time I might just have Roddy "look" at the exhaust .... :) (in fact I will probably stop in at Roddy to do the intercooler pipes for me)
who would you recommend to then "re-map" the engine for the intercooler and increased air flow ? (is it even needed?)

Re: Powerflow Exhaust system
I checked my invoice last night and I was mistaken, I paid R2200 for the branch and the piece of pipe from the branch up to the point where the torque box was removed.Powerflow Justin wrote:Everyone is entitled to their own opinion.

Re: Powerflow Exhaust system
Sorry but I am going to stick to my opinion and personal experience on this one, I cannot see the logic or theory behind the torque box, but I am not here to convince anyone that I am right. I have nothing to gain or lose, do you own research and make your own decision as long as you are happy at the end of the day.

Re: Powerflow Exhaust system
Recently bought a 04 Lux 2.7 with SAC chip and Powerflow branches etc done allready. One owner truck very well maintained. Yesterday I filled it to the brim and hit the N7 on our way to a farm near Misverstand dam. I'm not a fast driver, well not in a 4x4, to me every time I leave home in my truck is like going on holiday, and it was the same yesterday!! I cruised at 110 -120 km/h keeping the refs under 3000 rpm. Got back the afternoon after having done 252 km and filled up again, got 9.2 km/l. I could not believe this, because my previous truck (same yearmodel etc) use to give me 6 km/l.
Must also say that this bakkie is fairly standard, but this will help for them overlanding trips, even if it does come down to 6.5 or 7 when loaded. Will get in under the truck and see what have been removed and what not!!
