New tune for new exhaust?

stephenf121 · 10-12-2015, 01:19 AM

Hello,
I recently purchased a 2007 335i with a proceed rev3 running a custom wedge tune. It has catless downpipes, upgraded intercooler, charge pipe, intake, etc, but it has the factory exhaust. The car runs awesome but i wish it sounded a little louder. If i were to add an exhaust (catback most likely) would it require a retune, or do you think it would be ok with out? What about doing the golf tee mod or modifying the stock exhaust like this http://www.e90post.com/forums/showth...light=golf+tee I searched around and couldn't find an answer. Thanks in advance.

Exhausts past the downpipes don't do much in terms of performance on these cars, more for sound than anything else.

thanks for the responses. Sound is all I'm looking for, just didn't want to have to get a new tune made.
