Hey guys I just bought a K&N air intake kit for my 2003 F-150 Screw 4x2 V8 uh 5.4L or 4.6L (sorry not sure) the intake fits both engines. I will have to check if it make a big difference for what I am asking you guys). Anyways I want to get a nice deep sounding exhaust system just from the cat back, I want it to sound good but also work good. Any suggestion? I was also think of going with a dual exhaust what do you guys think? Any suggestion would help.

 

Is interior resonance an issue? How about materials (aluminized versus stainless)? I ran a Gibson catback on my old 01 F150, and I liked it. It was very quiet in the cab, but had a low rumble at the tailpipe..very refined. If you check out the link in my signature, you can hear some clips of my current bronco, with a Gibson catback. It will obviously be a bit louder than your application (since you dont have the other exhaust components), but it should give you an idea. I have both internal and external sound clips.
