i can just buy the muffler right is there any performance differnce between the muffler and the cat back and is there any differnce in the sound i am just on a budget but im so tired of not being able to hear my car i have already cut the cats and how does it sound with the cats cut??!?!?!

 

Huh?!

 

i second that

 

you cut the cats , you tell us how it sounds

 

sorry just thinking about several things at once is there any performance differnce between the catback system and just the muffler

 

The SLP Loudmouth has no muffler, it's a resonated system.
