adamsison 0 Report post Posted April 26, 2006 i heard that e36 m3 exhausts swap for normal m50 (2.5L) exhausts? is this true? and how much better performance would it give? any thoughts regards Quote Share this post Link to post Share on other sites

From what I've heard an exhaust on its own doesnt put out too much horsepower gain without being in tandum with an entire setup from headers right through to exhaust, only then I believe you'd be able to put out a noticeable difference in horsepower.
