We have finished our final prototype exhuast system for the E92 M3 from the headers back. We will be offering two systems, one from the rear section back and this one from the headers back. The rear section is designed for your everyday customer who cares more for the overall look and sound more than power. If you're looking for more power and don't mind a system that's a bit louder, the header back system is the way to go. The header back system is designed with ASR Stainless primary cats, ASR resonator with X-pipe, secondary cat deletes, and ASR mufflers with 92mm dual tips. The whole system is made of tig welded T304 Stainless and will not shoe any CEL codes for the cats because of our 02 bung design. We will be offering the same exhaust system for the E90 and the E93 as well.
The dyno sheet attached is of a bone stock car E92 M3 with stock exhaust vs. the same car with our exhaust system. Notice the 6200rpm mark, we gained an additional 30whp and 26wt. Overall peak was 21whp and 17wt.
The cost of both systems will be posted shortly once we figure out our production costs. We should have them available and in stock by next month sometime.
