I love my Borla system, it sounds great and gave the truck a bit more performance, costs quite a bit more than a flowmaster or magnaflowthough

 

i like a single in single out in the stock location....mostly because u see 2 pipes coming out of the back and u know its gonna be loud truck....
if u have a stock looking exhaust then u dont know how sweet it will sound when u step on it....
...i think ive also been disapointed a few times when ive seen dual out the back of a truck and it doenst sound too good

 

I just put a thrush glass pack righ ott the cats. straigh thru to elbow in front of the rear tire then topped it off with a chrome resinator. sweet and mellow normal can talk and radio low, But when ya tromp on it it opens and really barks. Oh yea it cost me 100 for parts and i have a lift so labor free.
