This was my plan/though process.
Exhaust manifolds to 2 1/4 pipes, muffler just behind the cab. Then reducing down to 2" tailpipes.
I was looking at the Brockman steel/glasspacks, and running true dual exhaust out the back.
Is this a good plan? Should I keep 2 1/4 pipes for the tailpipe, should I reduce it to 2" (thinking that the exhaust gasses would be cooling down at this point so a smaller pipe would be sufficient).

Don't make my mistake if you are going to install a spare tire carrier--Bill | | |
