Should I get a custom exhaust for my M3?

A buddy of mine had a custom exhaust system put on his 550i and it sounds amazing. I'm thinking about doing the same for my M3. Any opinions about custom exhuast systems?

I agree with PG that it's a science you don't want to trust your local muffler shop or tuner with. There are so many competent systems out there from reputable exhaust companies, I don't see the advantage, and see a lot of potential disadvantages.

I went with the Eisenmann system for my M3. It sounds great. I haven't done any dyno runs so I'm not sure if it makes power but it feels ok on the butt dyno to me. I doubt a muffler would add much hp either way.

Thanks for the input guys.

Some of you are not getting what I mean when I say custom. What I mean by custom is taking it to a shop and having them build one for me instead of buying a system straight from the factory already specifically made for the M3. Remus, eisenmann, etc. ...just to clarify. But then again, I guess a Remus or Eisenmann exhaust could be considered custom as well.

My main concern by taking it to a local shop and having a custom exhaust built is whether or not I would lose performance in any way...
