Any of you 5.0 guys have the SLP loudmouth exhaust or know of someone that has that exhaust? I want to know if there is any power gains with the system, thinking about the LM1 system since i have cats. As of right now im running flowmasters, not sure what series tho. Thanks guys.

It wouldnt be enough to make you change exhaust. Just do it if you want a different sound or dont like what you got. Other than that you arent gonna notice anything other than sound.
