I've got Dynomax headers, dual Magnaflow mufflers, and my truck just sounds so weak. I like the nice, deep rumble that you hear coming from hotrods. How much does your motor have to do with the way your truck sounds? I am going to get my crate motor installed later this year. Do low compression motors sound different than high comp? Does the camshaft have anything to do with sound? It's not that it's just sound I'm going for, I like performance first and foremost. But most high performance vehicles sound really good, meanwhile mine sounds like a stock Toyota Tacoma.
