    Stepped band clamps 2 3" and 2 2 1/2" if I remember correctly. You can get away with only getting 2 2 1/2" band clamps if you weld the downpipe together. And probably some Ultra Copper RTV silicone.
    And you cant use a ZZP downpipe with SD headers. You are thinking of the 3" ZZP flex pipe. Some people have issues with the SD Flex leaking or ticking.

    Just need better clamps like Slick stated..get Napa easy clamps unless you find those same style cheaper elsewhere. The clamps the SD come with are crappy.

    They come with a downpipe that is 3in from the rear collector down, then that has a reducer to bolt up to cat-back system.

    They don't come with a cat converter so you will need to figure that part out.

    The Flex pipe is 3in and if you wanted to swap it for a doubled walled flex, zzp sells them for 25 bucks????? then you just need it welded in place of the old one.

    the sd flex leaks over time. so its your choice, replace the flex now, or do it later when its harder to get too. and you need a o2 extension.

    I did not need the o2 extension
    I tried using the sd clamps... leaky so I got band clamps.
    Crossover did not align properly so had to use a thick chunk of wood to help bend it into place.
