My muffler while driving on the highway fell off coming from the cat. It broke at the end of the pipe coming from the cat and I just took out the whole system because it was so rusted out. Any recommendations on what I should do. I'm think of running an intermediate pipe from the cat straight to an oem exhaust pipe. Anyone know if this is the best way to do this. As well what is the pipe off the cat size and the oem exhaust size? Im pretty sure I'll need an adapter to go from one to the other. Thank you.

Early 5.7 engines were a single 3" inside diameter where it slips onto the converter. The least expensive fix is put a 3" race Bullitt/glasspack on it,get a 45 degree 3" exit in front of the rear tire..but I am a red neck that works at a muffler shop..lol


When in doubt..get the sawzall out..
