408 with tti's. Do I go with H or X pipe exhaust

mistreta said
Just put a Stroker in an 70 Duster, and I want to do the exhaust. I hear a 2 1/2 exhaust with an X pipe is the way to go. I heard the X works better than the H. Anyone have the X pipe on an A body? I'm concerned about the fit, do I have enough room?

I have a X on a 67 cuda with no issues. The pipe comes off the headers are 3" and is reduced to a 2.5" at the X pipe.
