3 1/2 inch Bullit Muffler's with tailpipes and tips. Muffler's dump in front of rear. But I still have the tail pipes hooked up into the turn downs. The car is loud but it sounds like its is comming from the tail pipes because they are tied in. You can also feel the exhaust coming out the tail pipes. The evac system works great. And the police leave me go when I drive it on the street.
