exhaust

Whats a good xhaust for the e36 m3  

Several people have told me that the best performing system for the e36 M3 is the B&B system. The same people will usually admit that the B&B system isn't the best sounding exhaust out there. As far as sound and performance, I would go with a Dinan system. I doubt your going to get much more than 10 or 12hp out of any exhaust, but it will give you a little more gain with more mods. Another good part of an exhaust upgrade is the weight loss. Factory exhaust systems are usually quite a bit heavier than they need to be. You should be able to lose at least 20lbs with an aftermarket exhaust.
