Well... I blew up my stock muffler - literally- back tailpipe go clogged up with 6 inches of clay mud. So now I need another...fast because it's starting to melt the carpet directly above the blown muffler. Anyway - I wouldn't normally switch out a good stock one for a flowmaster or blowmaster or whatever they call them now, but while I'm here I might as well improve a bit and re route the stock deal. A reasonable amount of added noise is OK. So that is my question. Some folks have previously mentioned switching to a single high flow and 2.5" pipe. But what is the best way to route this? My 62 has 2 cats, one on each side of the frame rail and then the outer one crosses under the rail and they wye into each other. How can I delete this part? Where's the best spot for the O2 sensor? Should I get a header?-- I'll do that if the cost isn't too bad. Just would like to keep the total bill around $600 or less. BTW- No smog testing here. (Da brothers wouldn't have nuttin ta drive then).
