Default Hooker Y pipe

Do you cut the exsisting Y-pipe tibe tube off and clamp to the new hooker Y-pipe?

How do you join the new Hooker Y pipe to the exsiting cat flange?

Yeah the 85 has the crazy flange with 4-bolts, I may have to cut off the old tube and weld the flange to it.

I switched to the 86 up cat and got a high flow cat and rear y-pipe at the same time. It slips on nicely. After fit up I welded the cat to the Hooker y-pipe.
