Happy Holiday! I'm getting ready to purchase a Gibson side swept cat back, and already have a K&N cold air kit installed. I'm just curious if anyone else is running that setup? My poor 4.6 can't even chirp the tires,lol. Anyways, I hope between the two performance upgrades to see a noticeable gain in power and sound.

BTW mine is a 2003 XLT with 4dr and 4x4 with the mighty 4.6
