I am going to buy headers soon, I have an SLP y-pipe on now. Will kooks fit my stock cats and SLP y- pipe or do I need to get the kooks cats and y-pipe? Also how about the ARH? Can I use the SLP Y-pipe or do I need to get the same brand cats and Y-pipe as the headers are?

you need to get a catted-y or an ORY pipe. The SLP Y-pipe won't fit unless you hack the **** out of it. Regardless, your stock cats won't fit at all. I beliebe KOOKS has a catter-y you can buy as well

the collectors on arh and kooks are 3". that slp y-pipe is meant for stock exhaust manifolds, which are 2.25".
