It was an off road X pipe

Mr.Ski

I put a MRT h pipe with hi flow cats on mine... it must have helped some - my boost dropped by 1/2 lb, which means less back pressure. They did give the exhaust a little deeper sound too.

I went with magna flo catted x and was very happy with it. Saw a bumb up in gas mileage with everything and enjoyed some extra power from it also. It sounded great. Currently i have run pypes catted x because i needed metallic cats for the supercharged. Personly i dont like the sound of the off road set up.

I found out there's a big difference in sound between the stock cats and high-flow ones...The cats on my Magnaflow X pipe are about half the size of the stockers.

Yeah I loved that sound too! Maybe I will have to look into trying the catted X instead of the off road one I currently have sitting in my garage

I wanted to post this video under this thread for future mustang owners wondering how a JBA header system matched with a Magniflow exhaust would sound:
