im not too sure about the Y-pipe thing, it would look sick as a set of quad exhausts, but you might lose a lot of power due to the lack of backpressure


wait a minute...isn't back pressure a bad thing? I feel like this was already a topic on the forum and didn't it say that back pressure is a BAD thing...

i think that for 325i and maybe 323i, the only purpose the muffler serves is to reduce noise emmisions. it does not seem to emit a light, as im sure they would have mentioned it in their above posts

i have a 2007 328i 2door and i just deleted the muffler only and im happy with the results.You get hp gain and sound too. If i would have deleted the resonator it would be to loud. i have pictures and sound clips check them out. i have them posted on pages 2-3-4.

Its a little raspy, but fuck, why did I spend a grand on muffler again?

Great job, who would'a thunk it.

sounds like an E36 with a blown out muffler if you ask me. Eisenmann sounds way the heck better...
