I am just curious if it is worth the $300 to put on an uncatted X-pipe from Roush on my stage II- I like the sound now, but I want a much deeper rumble than what is produced on my side exhaust H-pipe with cats and Magnaflow mufflers- Is it worth it to buy the Roush X or should I just get a random pipe (i.e. from Steeda) for half that price- does it really even matter????
