Review on 🔧 DNA Motoring OEM-CONV-002: Factory Style Catalytic Converter Y-Pipe for 07-09 Silverado Tahoe Sierra 4.8 5.3 6.0L by Ryan Whatley

08 Silverado 1500 5.3 4x4 Seen a lot of bad reviews. So far, so good. Fits perfectly, screws are ok, all required seals. No screws. If you leave all the regular screws. However, there are only holes in the tail section, and the original has pressed-in bolts, so you'll probably need some for that. A small note on removal and installation. Don't put anything in the new one until it's installed. Slide all fasteners into place before tightening. I would screw in the center cross pipe first, then the exhaust manifold ports, and then the tail. Also, take a jack and place it under the back of the gearbox. Then lower the crossmember/gearbox mount. It may take some time for the codes to appear in the vehicle. Let the pipes and sensors settle.
