I need (want) true dual exhaust that is professional grade....however since my Blazer is a 1990 5.7 TBI, no muffler shop will do it since it it only has one cat. I heard that I can order a dual exhaust kit for a 6.2 diesel and that will bolt right up to my stock manifold. I am a cop so ....finding that crooked muffler shop seen on 60 minutes and Dateline won't work....HA HA I live in Wyoming and we have no emissions test so I can get by that obstacle.HELP ME. Real four wheelers don't need tools to remove body panels, paint, tail lights..etc. P.S. Ask me why it is called "BODY SNATCHER"
