SFREW62

NemesisC5, Hey aren't you on the Corvette Forum also? Name sounds very familiar.....As far as the sound clip goes, I have already removed the y-pipe and boxed it back up in its original box. I would describe the sound with it on as being deeper and more performance oriented. It was loud on initial start up but after that it just sounded really good. Like I said earlier, it woke the truck up. The throttle response was better and it reached rpm much quicker. If you know anybody that might be interested, I am going to sell it for half of what I have in it. I am going to price it at $450 shipped. At most it has 2-300 miles on it. My user name on the Corvette Forum is SDF if you want to look me up. I have to have 50 posts on here before I can put it in the "For Sale" section. Thanks for the reply............

I have the Elite S2 on my 2017 Sierra. Definitely worth the investment! Install was very straight forward and didn't take long...............

Hey Guys , New to this Forum but a long time member of the Corvette Forum. I have a 2017 Sierra "All Terrain" with the factory cat back option at the time. Its marketed by GM but I think its made by Corsa. I also added the "Twisted Steel" Y-Pipe that AFE makes with the high flow cats. It really woke the truck up and got rid of the flattened out part of the exhaust I can't stand. The problem is, after a couple of weeks, it has started to throw codes as the cats flow faster than the two O2 sensors are calibrated for. Initially I was told the truck wouldn't require a tune, but now it appears otherwise. I am not willing to trade my warranty for a tune as of yet. I am going to sell my slightly used Y-Pipe and return to stock. Has anybody else used that set-up and not experienced any issues?? Thanks in advance...........
