I know... I've done a search... I've done the reading, but I'm still wondering about what the concensus is on exhaust mods for my '05 LLY? I want to get rid of the kitty, I want more efficiency, but... more than anything, I don't want to void my warranty. All the augmentations I've done to my truck can probably be UNDONE in about an hour if I have to take 'er in to the stealer. I want to keep it like that. I've read that trashing the cat will void my warranty; but do they actually check to see if it's still there if they don't (I have the Fingerstick) get any codes? I am perfectly willing to go with any recommendations. In a perrrrfect world I would trash the whole ex system and go with a 4" SS sys, but I don't know if I want to be switching systems just to go in for a loose mirror. I agree with a down-pipe from a LB7 or an aftermarket one, but gosh... for a few more bucks I can get a whole bunch more. Plus, I know what a b**** playing with heatrusted flange is. Go ahead, flog away!!! I know I'm sounding like a little spoiled kid who wants it all... but I do!!! As usual... any comments and/or suggestions are accepted and appreciated.
