Ok thank you very much I appreciate it. I think I did find the part I’ll have to remove everything an weld this part one

I have a 2015 Sierra 2500hd 6.0L. I have a rattle in the rear past the 2 catalytic converters and before the muffler. I’m curious if it is a 3rd catalytic converter?? It’s the red circle in the pic.

Hey guys I know this has been talked about before but I could not find it. I have a 2015 Sierra 2500hd with a leveling kit I’m upgrading my tires to Nitto the size I want to get is 285/75R18 will I have any rub while turning or anything? I didn’t want to cut anything. Thank you all in advance. Matt

2000 rpm cruising on highway. you wouldn’t happen to have a pic of how you did it, dimensions how long you made your tube? I know once we pull our camper the drone is going to be ridiculous . Thank soo much

I’ve been up most of the night doing a ridiculous amount of research an was thinking about installing the helmholtz resignator, any one ever hear of this?

I have a 2015 Sierra 2500 gas 6.0 ( I have no carpet, factory vinyl floor ) and recently installed a MBRP Cat Bak exhaust and holy cow I have serious drown on the highway at cruising speed. I’ve read reviews about this MBRP system an a lot of people said the drone was not bad at all. Anyone else have any similar problems? Thanks Matt

Went to a reputable exhaust company near my house. I mentioned I’m looking for a system that is not obnoxiously loud inside the truck only because I tow a 37’ camper an don’t want to be hearing that on a 3 hour road trip. (Guess I’m getting old ?) He mentioned a cat bak system called Xlerator. Anyone ever here of it or has one?

I have a 2015 Sierra 2500hd with 4:10 gears. Looking into getting a bigger camper an I Was wondering if a tuner or programmer would help with my towing. First What is the difference between the to. I can’t afford a Diesel or else I wouldn’t be asking this question. I live in PA an a friend of mine bought a programmer for his F-150 an the speed shop said he has to put his stock back in an drive 20 miles or so before his inspection or else it wouldn’t pass, what is that about and do you have to do this with a tuner as well, (like big bear) Thank you everyone in advance for your input
