| | | | Joined: Jul 2013 Posts: 388 'Bolter | | 'Bolter Joined: Jul 2013 Posts: 388 | I swapped in my Chevy 292 into my '54 3100. I am running 12bolt's dual exhaust manifolds, which lead to a 2 1/4" head pipe. I'm no exhaust expert, and the local shops have been less than helpful.
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). Help! | | |
