Cats really should be as close to the collectors as possible. If they're too far downstream, the exhaust gases won't be hot enough to propagate thorough catalytic reaction and burning off of the hydrocarbons, leading to carbon build-up that will clog the cats.

I'm kinda in the same boat as you. I have some Magnaflow cats that might would fit in the Y-pipe. I'm not chopping up my headers, but I'll slice and dice on the Y-pipe as needed. Already had to to install it.

Thank you for that info, it’s what I needed to know. I will do my best to fit them in after the collectors.

Not at the moment. Kinda wish I would have just went with the y pipe, the x pipe set up gets really close to the tranny, when it jumps back up over the other side. I bet it’s loud AF lol. I had 2 3” flow fx after the x pipe, really loved the sound at idle, but driving around was too much. I went with DI/DO 3” Maggie to tone it down. It technically has a double x pipe now, I know kinda stupid lol, but don’t know many ppl that had done it.
My y pipe also is close to my trans.

Maybe it’s speed engineering intermediate piping??? Cause the x pipe gets close like your y pipe

Little update, got them in. Just waiting to weld them up tomorrow and see what happens. Hopefully it doesn’t tone it down too much. I like the way it idles without them.

Is that crossover pipe sagging cuz of the slack in the slip couplings? It looks to be hanging dangerously low.

Probably. Long tubes with the y--all Speed Engineering pieces--were supposed to be compatible with my 4wd--a direct bolt on and go. It wasn't. Only thing I was happy about was the price of the headers.
