Just installed a Carven Competitor series axle dump catback. Removed the factory exhaust in one piece and installed the Carven in under a hour. Piece of cake. I was worried about all the posts saying you can't get the stock exhaust out in one piece without a lift. I didn't even use a jack or jack stand. Placed some ramps under the right side of the truck behind the front and rear tires, backed it up on the ramps, unbolted the clamp and removed the hangars. Slid it out from the front. No sound clips yet but I will say it sounds pretty good. Not obnoxious at all. Nice rumble. No drone..
