2002 GMC Sierra 1500 Exhaust Systems
Sierra 1500 Exhaust Tip: Adding a low-restriction muffler to an otherwise factory vehicle will improve throttle response, add horsepower, and often improve fuel economy (if you can keep your foot out of it, anyways).
Combining an exhaust system with an after-market air intake system is a good way to improve overall performance.
