predator 500
Are those Mac's mufflers tuned? I know the Ultra Thrusts and Red Jetts (Dub makes them to fit the OS bolt pattern) are tuned (with a mini-pipe inside). I saw a 32sx with an Ultrathrust, and it was a screamer. However, I am not sure it will it turn enough lumber to keep up with a piped 46 on a Predator.
