You could also put your catback on with a HFC instead of the TP. It might help a bit with the sound, while still giving you nearly the same gains.

 

The X cat is really pretty darn good. From what I've seen at Dyno4mance testing, the aftermarket ones aren't any better at all.

I really like the Ultimate bits, and they are not loud, per se. The deal is what is loud to me and what is loud to my wife are clearly two different things. Heck, she thinks a stock Evo is loud, LOL.

 

^^^ Anybody running the Road Race Engineering Bling Sideways Style? I like the way it looks. If i had this with the stock cat how close would it be to stock (as far as sound)? If a 1 was stock and a 10 was a TBE(DP, Test pipe, and exhaust)?
