2002 Silverado 2500HD ECSB 8.1L 4x4
I have a Gibson catback on my 2002 2500HD ECSB 8.1L. No cats. It was horribly loud and raspy after install, added 2 Vibrant resonators before the muffler. This made it tolerable around town but it's nauseating on the highway. I'm looking for suggestions on an aftermarket muffler or catback that will give me a little more sound than stock but not deafen me like the Gibson. Thanks!
