I have a better idea
Why don't you get some of those resonating fart cans and bolt them straight to your X-Pipe
Knowing how loud and crappy those sound bolted to a single 2" exhaust pipe, I wonder what it would be like bolting 2 of them straight to an un-mufflered V-8. Probably like one of the race lawnmowers instead of the weed whackers that the Honda's sound like
ok, sorry, i just felt like talking
