Somewhat new to Performancetrucks.net, but not to LS1tech. Working on swapping a 6.2 L94 with Tick Performance Tow Max cam into a 2008 PPV Tahoe, at the same time, I would like to upgrade the transmission to a 4L80E. I just need some advise on the ARH 1 7/8" header and y-pipe setup I would like to install and see to what extent I would have to modify it to fit decently? If anybody has any experience with this, please feel free to post. We use this vehicle to tow a max weight of about 6000 lbs. Basically a car trailer with an F-body on it. Anything heavier, we borrow our parent's Duramax.

Just a few pics of the progress, got the crossmember painted and installed. The ARH 1 7/8" long tubes clear the y-pipe by a large margin which is great! Using the PCMofNC 4L60E to 4L80E conversion harness. Working on plumbing up the transmission cooler and fabbing up some cooler lines. Will have more pics as it progresses. The engine combo is a 6.2 L94 out of a '13 Denali, installed a Tick Tow Max cam, new Morel lifters, Melling Select oil pump, LS2 timing chain and tensioner, and PAC 1219x valve springs. I retained a stock 4L80E converter just due to the fact that we tow my wife's '99 Trans Am to the track with this truck. Has to trim the ear on the passenger side of the trans to clear the header.
Safety loop fits beautifully.
