Rep Power: 79 The sad part is the cost.
BTW I have for sale my OEM RSR headers and M&M silencer kit for RS.

Yes the Bypasses center sections sound great and the car loose good weight in the back no great HP gains,a really good alternative.
But I also want some extra HP,s and a good diet for the rear of the car....

We are testing our World Challenge header and cat system in about a week.
This is similar to our the system we use on the 3.8GT3RS cars now.
200 cell sport catalyst, equal length header system with 3/1 F! style merge collector.
http://www.gmgracing.com/porsche_exh...72header.shtml
Will post full report and dyno results before and after.
Stay Tuned!!!

Looking forward to this.
I want to see an RS 4.0 on the dyno with before and after numbers. This car cost way to much for a manufacture to say " it should do x" or "it should do y"
If you have it and can do it just show me.
Good luck and thanks.

If I had a 4.0 I would want to see a comparison for complete systems from the top 5 tuners for HP and Torque before I made a decision to spend 4k -14k on a complete system....
It is way too easy just to say systems for both 3.8 and 4.0 are the same and will provide the same data

Great Idea.....
We need 1 car to test all the systems in one day.
(In reality the chances of that happening are slim to none)
Bring the system's and I will gladly supply the Dyno time.
We have a proper dyno test cell and the repeatability is second to none.

We will post before ,after pictures along with video and dyno results of our World Challenge header and cat system for the 4.0.
