In Reply to: KC///M3...about those straight pipes! posted by [email protected] on April 26, 2000 at 14:03:46:

: Sorry for the delay, its a busy time! Well the straight pipes are from the cat back...they bolt on just like a cat back system would. They are fabricated of 2.25 inch mandrel bent mild steel. The reason we decided to go for mild steel is because we figure that the SP will most likely be used on the track only. It is loud and would take some getting used to on the street, like I said before it sounds like a race car. The mild steel not only is lighter than Stainless but is A LOT cheaper. Like a quarter of the price. If you were to use the SP as a full time system, you could still figure at least 5-6 years out of it. I mean the stock systems are not stainless and still last long. These pipes are of a thick guage so that is another plus in the longevity department. We also double coat the piping with black hi-temp anti-corrosion paint for an added protection. We will be testing them in the next few weeks. I will have numbers comparing the stock system versus the SPs...I will also try to get my hands on a popular aftermarket system to see how the straights do against that, since aftermarket numbers on pretty much EVERY upgrade on the M3s have been blown out of proportion lately. I want to get the facts straight, no punn intended :-). Until testing is done and we are happy with the results their will be no pricing available. We are still tinkering with this and are trying to find the best possible cofiguration of pipe diameters and bend angles. Mind you, the straight pipes will make a bigger difference as you do more mods to the car, as it will require to flow more air out. That is a pretty self explanatory concept though. As soon as we get the test results, l will post the findings for everyone to see. I'll keep you posted on the progress. And if you have any other questions or if anything is unclear let me know.
: On a side note: We are also debating the possibility of testing both OBD1 and OBD2 chips on the dyno from a few known manufacturers and others not that well known. Not sure when though. These OBD2 numbers specially, are an insult to the inteligence of anyone on this board. But overall the HP gains claimed by manufactures on a lot of their upgrades are doubled sometimes tripled of what actual dyno tests show....other times not even proven!!!! Finding out what the real numbers are can't hurt and will only be to the benefit of everyone. Not trying to start a war only in search for the truth.
