Gibson Exhaust 5657

Just curious if anyone has any experience with Gibson Exhaust Systems? Specifically the GIB 5657... Good or Bad...

Gibson makes high quality systems that fit really well. I put a dual sport cat back on mine and the install was really easy and it fit my truck perfectly. It looks like the system you're looking at has the same muffler as mine except yours splits and goes out the back... I think it would sound pretty good on a stock truck. A little loud for some people's taste but not too bad. I can tell you if you're boosted it does change the exhaust sound quite a bit. On mine if I keep it out of boost its okay but as soon as it builds boost, it cracks pretty good.
