Very happy with thr outlaw system from flowmaster. Had it installed at a local muffler shop and had them weld it up to insure no exhaust leaks. Sounds killer and would recommend it to anyone looking for a good exhaust system. Its not too loud in the cab either like I thought it would be. Its perfect!
