Aftermarket 3" Dual Exhaust Systems?

Anyone bought and installed one of those kits like you see advertised in Hot Rod magazine, or on the Summit website?
Wanting to know how well they fit, what brand you got, and any issues you had doing the install.

Thinking of the ones that go from the headers on back, (with or without mufflers), or maybe just the rear tailpipe sections that go from the muffler to the rear bumper.
Needing to get a 70 Chevelle through state inspection here in Texas, and they won't pass anything where the exhaust doesn't go past the rear axle.
Car has turbo mufflers and turn-downs on it now. Antique cars don't have to pass any emissions test or inspection, just the "Safety" inspection. (Which includes the exhaust).

Thanks in advance! -Jim.

Jim, I would suggest you register on teamchevelle.com for more accurate info.

I did a Flowmaster header back system for my '65 4-4-2. It was a 2 1/2 inch for the "A" body. It was a great fit except for the short cross over pipe as the drive shaft would hit it when on a lift with the rear end hanging down?? Had to cut it out a make one with a bend in it to clear.
