Mixed pipe diameter
I restored my 72 Lemans vert T41 with a stock 2 1/4" exhaust system. I did this whole frame off myself in my garage. I was going to drive it to town to have an exhaust put on, then decided I could do that too. But, I wanted zero problems with fit. So, hence the stock replacement. Now, with the 400 dyno at 310 HP and 400 ft. lbs. torque, I feel I've cheated myself on the performance end with the exhaust. I'd like to up to a 2 1/2" system and different flowing mufflers. I had to make my own rear tail pipe hangers going out the sides, so I have to make sure those work. My thought now is, am I cheating my self if I just change my down pipes from stock manifolds and new mufflers, but keep my 2 1/4" tail pipes?
