If you want a light muffler that barks, our 850 E-TEC turbo muffler is the way to go! They only weigh 5lbs and they fit great with laser cut mounting brackets. All of our mufflers are dyno tested and airflow tested on our Superflow to make sure that they don't lose power as many others do. This muffler is light and loud, so please use it in areas that will allow for it. The muffler is equipped with a factory sensor bung.
