thanks alot guys for all your replies on my thread. ive decided to run with jet hot headers and loudmouth definitely. and i needed a y pipe. and i hear you can only run jet hots with the hooker y pipe. i need to run a y pipe with some hi flow cats. so is it good to go if i get hooker y pipe and weld in hi flow cats?

 

That's going to be insanely loud. But some people like it that way.

Anyways, yeah you cut buy a Hooker y-pipe and weld in the cats. I'd suggest just having a local exhaust shop fab up a ypipe for you. If they're good, they'll make a better one than Hooker's for probably a little less than you would pay.
