Mr. Vroom Report post Posted October 23, 2010 This Jay Leno vid has the best sound recording of the exhaust I have heard so far: And the Renntech exhaust, supposedly has an ecu tune as well, but so far no power claims made, sounds ok, but missing the backfires!

57udl3y Report post Posted October 23, 2010 it doesn't sound all that much better, wonder what the gains will be to make it more worth it Quote Share this post Link to post Share on other sites More sharing options...
Mr. Vroom Report post Posted October 27, 2010 I called up Renntech, they claim a gain of 45 hp and 45 torque..... Here is their dyno sheet, which is kinda suspect, because Edwards Inside line dynoed a stock SLS on the same type dynojet and the stock made more hp than the tuned Rennetch! Guess I will have to dyno my car first! http://blogs.insideline.com/straightline/2...nz-sls-amg.html Quote Share this post Link to post Share on other sites More sharing options...
Modo Report post Posted October 27, 2010 If you want more sound and backfire, take out the resonators Quote Share this post Link to post Share on other sites More sharing options...
