UPDATE: Decided to keep it until after downpipes are installed to see if I like the new sound or not.
If I get my new exhaust then I'll be selling the stock 335is exhaust. Just mufflers only and no pipes. I just wanted to give you guys heads up and see if people are interested. Also PM me offers since I don't know used prices for the exhaust.
Based on my research here are the part numbers: RealOEM Website
Separately, the mufflers are $420 and $320 for left and right plus the extra for clamps etc.
Tischer sells them as a package for $695: Tischer URL
Since I am ASSUMING that I don't have at least 2 of the 3 clamps, I am deducting $100 from the Tischer package price. So assuming it is $600 new, I am hoping to get around $350 for my used one. Is that fair? I haven't seen many 335is exhausts for sale.
