Hey guys. I have a hp 300 with a hedman header with 6 into 2 collectors. Currently I am running two 2.25" tubes into one, and through the old round muffler that was on the original 390 engine.
I would like it to have a healthy low sound, but to still be quiet in the cab. Does anyone have any suggestions?
