Dual Exhaust Conversion

I don't know what TTI has for A-bodies, but I know they offer a full dual exhaust for B-Bodies, and I'm planning to use one of their kits on my Charger. For the B-Bodies, they offer a kit that goes from the exhaust manifolds out the back with either an X or H crossover pipe. A bit costly, but really not much more than it cost me to have a custom system built, and TTI uses mandrel bent pipes instead of the standard bend pipes I got.

Might check to see what they offer for your Barracuda
