I have two different 440 powered vehicles an exhaust system sound so completely different between them. they both have the same size exhaust, same 20" super turbo mufflers, same headers, one has an engle K 54 cam the other one has a another cam with almost identical specs, both low compression 452 head engines. the only other difference is one has an x pipe one has an H pipe. Vehicle with the H pipe is regular exhaust shop bent tubing the one with the x pipe is all mandrel bends. I can't believe that the x pipe vs. H pipe could be the only thing making the difference. The truck sounds absolutely fabulous Good Old School Rumble has a bit of a roar when you get on it the other vehicle almost sounds like crappy mufflers and is annoyingly loud when you get on it. Both complete systems are 2 years old that I installed so it's not like one of them is really old or something like that. Any ideas why such a difference.
And then of course my 67 RT which has I believe accurate exhaust on it sounds good also but has a little bit of a drone certain RPMs
