Exhaust Y-pipe

[ktm1217]

Well, i think the final decision has been made...im gonna have to either replace my y-pipe or get a new cat. Ive welded the pipe off the back of the cat twice, and its only held for a few days, then falls off again. I think ill be able to cut off the cat and put a new one on the stock Y-pipe, and then run the rest of my exhaust off that. Ill prob do 3" into the muffler which will be a Flowmaster Super 44, with 2.5" dual outlets, and exit it at a 45* in front of the rear tires either on both sides or bring em both out on the passenger side. The other option is to just do the Super 44 with a 2.5" single outlet. But either way, Id like to bring it out at a 45* in front of the rear tires.

As for the cat, its the factory one that was hollowed by the previous owner. But Im not sure if the Y-pipe in front of the cat is 3"...? I know after the cat is 3" though. And i think i might throw a high flow on it. Any ideas on this setup??

The way the Y pipe is set up is its a two pipes in to the cat and single outlet cat. the Y pipe is 2 inch.
