Included in each of our 2012 Stage IV Exhausts is our newly redesigned Stage IV Exhaust Packing. The specially formulated compounds in the material allow for superior burn resistance and longevity; lasting 2 to 3 times longer than industry standard packing. On top of that, the extremely simple design makes repacking a Trinity muffler quick and easy...just a few minutes max!
