I have a 1994 318iS and the exhaust makes too much noice. I removed the exhaust and small chips of metal-like (they broke really easy with my hands, so i dion't think it's actually metal, maybe filter or somehitng) material that came off from the inside of the muffler. I want to replace the muffle but i dont know of any good ones. I don't want to spend too much on it either, ideally less than $300. I was looking at this one Bosal Exhaust
. I was wondering if any of you know of any good mufflers or know about the quality of hte bosal exhaust on the link. I appreciate any comments or hints that could help me. Thank you in advance.
