I am finally getting my exhaust installed I'm going with hooker long tubes and true duel with a x pipe and cats to out through dynomax bullet mufflers.My Question is will the cats kill alot of my cam lope?These are high flow cats I wasn't going to install the cats but I figured it would help keep the car a little quieter.Thanx in advance

 

The cats will quiet it some but not much just won't sound as choppy, the bullet mufflers are race mufflers all they are going to do is take the edge off a little. If you don't use the cats and just use the bullets your car will be loud as hell.
