I finished up my huge motor project in my dad's 1999 k2500 suburban with the 7.4 liter 454 vortec engine. Now I started it and went to inspection. He told me I need a new exhaust because of the severe rust. I looked under it at home and I couldn't agree more. When I started it the first time I had rust flakes flying around. Anyhow the problem now is to find an exhaust. I can't manage to find an exhaust anywhere in the Internet. Not on rock Auto, AutoZone, flow master etc. It currently has a flow master system but I can't see any kind of serial number or similar could also just be the muffler itself. Adding on to that it also has Edelbrock headers. Any links for exhausts would be great. The cheaper and noiser the better but I don't want a full straight pipe
