Lets see your exhaust tips
Before and after mini tub the tips were re-installed at the correct angle and distance from the bumper.
All after market tips I see have to long of an L bracket that need to be shortened for a-bodies. They all come through with b-body L's which let them hang to low.
These are the correct distance from the bumper in the pics. Some cars I see the tips look as if the are used for wheelie bars.
I had to narrow the fuel tank to reuse the tail pipes . These are still hooked into the turn downs under the car so it appears and sounds like the exhaust flows through them. Yes some exhaust does flow through them. The car has 2 inch to 3 1/2 exhaust H pipe with 2 1/4 tailpipes.
This exhaust with tips still allows allows 8500 to 9000 rpm's with 456 gears and a 5500 converter.
