RENNtech stainless steel (SS) sport mufflers are hand made and rigorously tested to provide maximum performance, dramatically reduce weight and produce an incredible sound.

Our freer flowing muffler weighs in at a scant 10 lbs per side in race configuration versus the factory mufflers which weigh in at a hefty 60 lbs per side. That is a reduction in weight of 100 pounds across the front of the vehicle versus the stock system!

Better sound, huge weight savings and a performance gain of 26 Hp and 33 Lb/Ft; our exhaust is the ultimate performance upgrade for your SLR.
