Currently looking into swapping out the exhaust downpipe and keeping everything else stock. I've been looking at the APR unit and wanted to know if it is MOT friendly? Its a bit 'pricey' at £694 so if anyone has an alternative suggestion please let me know. Main criteria is car must pass MOT and I don't want a boom box (...I'll leave that to the wannabe gangstas !!!). Thx.
