Out with the old, in with the new...

Just traded my 328i in today and picked up a 2011 M-sport 335xi. The modding begins again...

What's the best way to add some exhaust tone to the stock exhaust?

delete the secondary cats, it sounds great.

I have that and you gain some power....catless DP's give a bit more power and even better sound...

What's involved in doing this? Easy mod? Cost?

And if I do this, will the dealer give me crap about warranty issues when I bring it for service?

You can also do a muffler delete. Should cost you around 150 depending on where you go.

easy mod, no problems with the dealer what so ever, i deleted my 2ndary cats on my bmw performance exhaust, should cost you 200 at most just a little welding and cutting.

I have the N55 and was contemplating a exhaust upgrade especially the Performance one but, after doing the Golf Tee mod I was satisfied (For the time being so far lol)
