As you can see in my sig I have a magnaflow cat back exhaust on my truck. Does anyone make a cat delete pipe that will work with that exhaust system? The magnaflow butts up against the stock pipe, it does not slip inside or over it, and then you reinstall the stock band clamp. I never thought I would want to run without a cat when I bought it, but I changed my mind:rolleyes: and would like to hear what it sounds like. Thanks!

MBRP's will work almost any front pipe will work i would just get one measure out from the down pipe to the muffler then put the new pipe on and measure it again if to long then cut to fit

Only problem I could see is that my magnaflow necks down to butt up against the factory cat pipe. Would it still work?

Does your cat back have a 4 bolt flange? If so, I'm pretty sure that you can use a stock LB7 down pipe. Maybe not on an LBZ. Someone correct me if I'm wrong. (BTW, I have an extra if it will work.)
