Does anyone have a fully catless set up on their 5.3? Currently I run a catback that deletes the resonator and muffler. I was looking at long tube catless headers and a catless y or x pipe. Want to hear a sound clip of it. Also what brands do you recommend I can only find kooks and they are about 2k for the headers and y pipe so I'd still need to get a catback system which is another couple hundred made at my local shop in friends with.
