siren676 Posted March 17, 2011 Posted March 17, 2011 Hi guys im looking to put a proper backbox on my car. My current one is just a straight through muffler with a 4" tip which doesnt really line up with the cutout.Mainly wanting to make the car sound better, the backbox will have to have a 2.25" inlet to fit my exhaust. It will have to work on a 5efhe as well.Currently sounds like this Any recommendations? Quote
