i was wondering if anyone has installed highflow cats onto their truck. i wan't a loud exhaust and i'm thinking about putting on a IMCO EXTREME muffler and i just wanted to know if i put high flow cats on with that if it would be any louder and worth the extra money?
thanks

 

Take two of the four cats off and leave them off. Replace the other two with a highflow (brand of your choice) and it will give it a little more deep sound.
