E9x M3 Exhaust
Vanguard Performance
Info: vanguard-performance.com
The growl of BMW's 4.0L V8 at 8k is already music to our ears, but add a quality exhaust and it becomes pure bliss. Vanguard Performance has released its titanium exhaust for the E9x models and it appears to be a stunner. Claiming close to 15hp gains over stock, the system shaves 25 lb over the factory system. Not only that, it looks pretty damn good, too. For added performance and the smooth symphony of German muscle, check out Vanguard's website for a dealer near you.
