Eric at Classic Chambered Exhaust made me a set of these 2.5" resonators to fit beside the gas tank on my 70 Challenger. He made them so that they would bolt onto my new 2.5" R/T exhaust tips. All I had to do is cut off the rear TTi exhaust pipe and clamp them on.
Very cool. What was the change in loudness and drone?
On A-bodies with full exhaust the leaf spring and gas tank barely fit 2 1/2" exhaust. So can go any wider than that. Can go up and downward for a box or oval type deal with the same width as the inlet and outlet diameters. Never seen a 2 1/2" resonator like that.
I was thinking something like this may work. They don't look that much larger in diameter, but I'll have to take a better look:
