loudmouth+slp Y-pipe...............What are the gains and sound?
Im looking for an exhaust system that will give a mean sound.
any inputs????

 

My friend has the exact setup you're asking about and it sounds FIERCE. He said he definitely gained some power from it and it flows much better than the stock system, but it's VERY loud.

 

Don't know about the y-pipe (a future consideration) but the SLP Loudmouth is one mean sounding exhaust!!! Had mine on for a week now with the center quad tips and it sounds awesome. Rattles windows as you pass by. The performance and throttle response improvements are also noticeable.

With the Y-pipe it can only be better!

edg1957 has the SLP loudmouth on his 02 and it sounds awesome, he may have a soundclip of it also.
