How did it sound with the jba shorties and the loudmouth? I currently have stock manifolds, y-pipe n cats with the loudmouth but i was thinking of buying some jba shorties and keeping my cats on there. any power gain?

 

as much as everyone says how much flowmaster blows mine sounds better then anything ive had on my 2 lt1 cars..with pacesetter LTs and offroad y pipe i can tell you right now if u like the sound of a mustang you'll probably wat to go with flowmaster or a similar sounding exhaust
