    Guessing a s3? If you going for a custom exhaust you may aswell go for 3", unless you want it tobe boomy though, you should get a miltek style backbox to help keep the noise down when cruising etc.

    3" might sound a bit boomy but wont do any harm. Might be OTT unless ur running big power. Im sure someone on here is running standard exhaust with 300+ bhp
