I am thinking about getting magnaflow high flow cats, magnaflow x-pipe, and I already have magnaflow magnapaks. I am wondering how loud they will be with that setup or will they become deeper in tone? I have a 2002 Mustang GT. thank-you. This is the exhuast I am looking at. http://www.latemodelrestoration.com/...-Catted-X-Pipe

 

I have the same x-pipes but with flowmasters. You'll love the sound. The high flow cats will give you a little bit of a deeper sound while cruising but during WOT is when it sounds sick! It won't be muffled by 4 cats so you can hear the high revs clean. I get people pulling up to me all the time that tell me how good it sounds. I highly recommend magnaflow x-pipes!

 

Any time that you choose a catted pipe, you'll get a deeper, cleaner sound that's not as raspy or loud as a o/r pipe.
