Aftermarket Exhausts

My2.2cents worth. The APS zorst is a good bit of kit granted. Whilst it may have been modified it probably ended being more efficient removing some of the ridiculous and not needed bends 

I'm sure the guys who did it are engineers and flow tested their results against the original exhaust.

As soon as someone drills a hole, cuts a pipe or bends a part of an engineered item it won't perform as to specification and therefore can't be used in any comaparisons with other hardware.

I suspect if someone bought a plenum, drilled some holes in it or bent some parts of it because it didn't fit right (according to the person who fitted it - funny how others don't have the same problems with the same product) then it would be pointless also to compare it to other products and make claims of power reduction/gains. I guess you won't agree though because it doesn't suit you.

but at the end of the day it delivered better than 30rwkw over the APS set up . Same Dyno , no if's but's or maybe's .BETTER, but it was what I wanted and what I gladly paid for.

So do you have a sworn statement from the United Nations that his is correct? No, I didn't think so. It's all lies.

Time to move on.... another degenerated thread.

All I can say is geese, think about this

take ONE maccas straw. now breathe thru it.

Im sure you can breathe thru it.

now take two. and breathe thru them.

much easier isnt it?

Just because a part isnt TOTALY restricting a combination from making power, doesnt mean it isnt a restriction.

Turbos can be decpetive as you can generally add a few psi at times to help conceal some smaller restrictions ( eg. standard intercooler plumbing ).

One little thing for you to go and research, is that straight pipe flows easier than bends. so banging on about its not standard and therefore must be sub-performing makes no sence.

Not everthing is engineered to perfection. sometimes things are made to budget ( shock horror! )

Humans ARE failable, therefore no one human build thing is going to even aproach, much less attain, perfection.

There are a couple of books on turbocharging, one being turbos by hugh mcinnes, and maximum boost ( I think ) by corky bell.

These two guys have forgotten more than most of us will know.

I strongly doubt that they or ANYONE who is half serious about attaining performance in a turbocharged setup wouldn't advocate the use of a better designed, LARGER dump pipe.

4000cc + 15 psi = lots of very hot and turbulent exhaust gasses to remove. I nearly fell over when I saw the design of the stock dump.. very cost driven design I think.

but anyway, feel free to disagree, argue, be stroppy or etc.

Facts are facts and being loyal to a company who nolonger holds the leading edge and bashin those that dare to speak against them is rather senseless. Its called competition, and that improves the breed.

He is the BURGER KING!

Geesy needs to sit down with a

and have a think about unichimp and APS. Then you may get an enlightened post from him. Then again, maybe all the trans fat has given him brain cancer and he can't think for himself anymore? Edited 25/02/07 10:54 PM by ENVY-T

to one of the most passionate and entertaining threads in a long time.

Thanks to everyone who participated. Jack, you said what many have been thinking. Geeseman, I have no doubt that you are the ultimate believer in APS, shame that you never took the blinkers off.

All we need now is DBOSS

I'm not trying to discredit an APS exhaust at all ... it has it's place .... but most of us have moved on and consider a good exhaust (especially for mid 300's power and upwards) as one that utilises a good dump pipe, not a stock one.

Like most all of your comments about APS gear brian they have no basis.

Fact is plenty of cars have made power at and near 400rwkw on the stock dump pipe, with one exhaust or another. A few of these cars have run 10 second passes as well. Why then is there a need to 'move on' when the existing standard hardware does the job?

←

Surely though, the car would make even more power with a good dump pipe or make the same power with lower boost. I'd rather do mods that make the most power at the lowest possible boost. If that means spending a bit more on a full exhaust so be it. I'd rather keep the turbo running at close to it's peak efficiency than keep putting more boost in. Less heat and more power.

[JP300]

Great thread ... my two cents worth.

I am sure that the factory dump pipe can flow 400+rwkw... but how efficient will the end result be? How hard is the engine/turbo going to have to run to push through that sort of power and how many times do you think you can do it before raising the temps through the roof!!

If you just want to make the power on a couple of dyno runs then no problem. If you are trying to build a tough street car which might cop a bit of stick every now and again then think again!
