If I swapper my regular 325i exhaust with an m3 exhaust(assuming it fits) would it provide horsepower gains or is it quite similar in restriction? I am wondering this because I can get an M3 exhaust for rather cheap and I am wondering if it would make sense to swap...

umm this is justo ut of my head, but i dont feel it would be worth the money to buy a m3 stock exhuast, some m3 parts such as cams etc are great to put on the 325, however a stock exhuast... not sure, someone please correct me if im wrongthough
I put one on my car.
I paid $400 CDN for a used one (installed).
It just bolts right on. I noticed they shaved a little bit off where it gets close to the tire. I was told I would get 5-8hp (don't know if this is true).
But it does sound nice and I do feel a slight gain (maybe it's just in my head).
yeah a lot of that stuff (the feeling it) with parts like exhuast and intake are in our heads... not saying its not there but you want it to be so bad that you do end up feeling it, anyways ive done research asked around on other forums etc, they say the hp gain is so minimum if any that part isnt worth it, they do say the sound will be different... so maybe if you want a different sound with it not soundling like a aftermarket like aatuning the m3 exhaust would be good for you. i however would not spend more than 50$ on a stock m3 exhuast for the stock different sound and no HP gain. That is just me
so it is a pretty common thing for people to do this...
Can i ask you guys that have why? not in a bad way just curious? are you ever planning of upgrading to an aftermarket performacne exhuast or not? did you just want a little different sound without the loudness of Aftermarket or what? just curious
Piping is bigger (just not at the part where it bolts up). M3 one is a lot heavier. Givin that the rest of your exhaust is stock: Sound is much quieter and no noticable gains. It does look better though. The only reason I put one on mine was because my stock one was shot and I found an M3 one with low mileage for 160$ and did not want to settle for a cheap ANSA or something that would rust out quick. So if your current muffler is in good shape I would suggest saving up for a Dinan, Supersprint, or whatever other good ones there are. You will not find a new good one for under 450$ though. Just my $00.02

I got one because I liked the look and the sound and I was told that I would get some gains. I do believe there would be some gains but as for how much, I don't really know.
But one thing is for sure, whenever I would turn my AC on the car felt sluggish and the shifting wasn't as smooth. Since I've put the M3 exhaust on that does not happen any more. That leads me to believe that there are some gains to be had.
