    I highly recommend ARH. I have them in my 08.

    I would love to get some AHR's, but they weren't much help when I talked to them. Not sure what size I need for my 5.3L. Also, not sure if I will have issues connecting to my Corsa exhaust.

    Have you spoken to BlackBear? Generally for a NA motor, 1 3/8 would be perfect. Going with a larger 1 7/8 could cause you to loose some power as it would be to large of a diameter. Unless you have a supercharger that can benefit from the larger piping and help flow.
    When I spoke to Justin at BlackBear, I was told that a NA can’t utilized the larger diameter of a 1 7/8 header without the help of a FI. Best to use 1 3/8 long headers for NA as shorties don’t do much for performance gains and use 1 7/8 for FI. This info was last body style Tahoes but I imagine it’s the same for yours.
    As far as Fitment, you shouldn’t have any problems. Unlike the stock y pipe that’s solid, the y section on my ARH has clamps so the pipes have some adjustablity to them. It should bolt up no problems.

    Have any problems dropping the trans pan? Looks a little tight.

    Nope not at All. That section of pipe comes off. So access to dropping the pan isn’t a problem. I also installed a pan that has a drain plug in it, I change fluid every 30k and drop the pan and replace the filter every other. No mess
