hey guys got a question on my 2003 gmc sierra got the stock exhaust just wondering if have any suggestions on what to use cat back system
?

 

it depends on what your looking for. when i got my truck flowmaster
only had the forceII system which is the mild system. now they offer
the aggressive one. i like mine its quiet but still has a nice tone to it.
easier to sneak up on someone.

 

Go with a Corsa. It may be expensive but I think it has the nicest sounding tone, never annoying. At WOT it sounds beautiful. Sometimes I roll my windows down just to appreciate the sound. The construction is also VERY nice.

Another system which looks nice BUT I dont know about its sound is the Magnaflow.

Like I said go with a Corsa, I love mine and I think you will too

 

you may also want to look into Bassaini systems

 

www.bbtriflo.com supposed to be awesome construction and theres a sound clip under the sights and sounds page
