I know a couple of y'all have the resonator delete kit and are happy with that. Does anyone have one of their complete cat back systems? They are on sale relatively cheap on eBay. The problem I have is the kit is for the 5.3L engine and I've got the 6.2L Denali. At one point I was told it's just a different bolt/mounting flange at the cats. Is this something that's easliy fixed and worth it or should I just keep shopping around?
