Wilbert350 Posted March 4, 2018 Share Posted March 4, 2018 Hi all, One question first: will an aftermarket Y pipe increase exhaust volume? I currently have a backbox but am far from willing to get rid of my cats, as it'll just be too loud and droning. I'd also be interested in some HFC, (quieter than test pipes as far as I can tell?) I can't be bothered with test pipes (MOT hassle). If anyone has a Y pipe (aftermarket) they want rid of, I'd be interested. Many thanks, Wilbert Quote Link to comment Share on other sites More sharing options...
Irn Bru Posted March 4, 2018 Share Posted March 4, 2018 Can't see a y pipe increasing noise by much, in fact if anything at all. If you can get hold of a Stillen Y pipe that would be great as they are well made and don't have flexi's to break Quote Link to comment Share on other sites More sharing options...
