Exhaust Note

Exhaust note from the AMC 360 in my 1987 Jeep J-20 Pickup, with a custom stainless 2.5" single exhaust and a Magnaflow muffler.

Question, why the smaller 2.5' vs 3' any reason Your videos are great It sounds nice

Yes, I am using the stock Y-pipe on a stock 360 2-bbl, which will rarely rev above 4000rpm. A true 2.5" exhaust will provide plenty of flow for that application. There would have been little to no advantage to a full 3" exhaust.
