Question for you folks that might know. What aftermarket muffler will produce the most masculine sound at low RPMs? I don't race, but I want to be noticed. Your thoughts? If I sound like a novice, it's because I am.

And you really wouldn't be gaining *that* much over the 3.6L V6 (same HP as the LS4 V8 - but less torque).

Correction: you'd be gaining a freaking 5.3L V8 and all the giggles that go along with it! it would giggles per gallon and smiles for miles for sure. LOL

Worth it!!! IMO
