Correct me if im wrong but a new y pipe to accomodate hooker lt's would stick my cat in the middle? I have a question. My dad is douching and wants me to cat it. Instead of wasting on a catted-y can i get one of those small ass cats and stick it in the center?

Dont stock cats have to deal with that anyway? Dont they get the flow from both sides.

Yep, 95 and earlier cars only had one cat. If you get a big enough diameter cat, and its high flow, it won't hurt you that much. THe whole point of headers, other than scavenging, is to space out the exhaust pulses so they "fit" through the exhaust system better rather than all jamming up together.

The biggest problem with your plan is that the cat is going to be so far downstream it may have trouble reaching light off temp. I'd recommend a high temp ceramic coating o the headers and Y pipe to keep as much heat in the gases as possible, and you'll want the cat as far forward as you can get it.

I'd rather you do two single cats right after the collectors though. YOu could even flange them and take them off in place of off road pipes when not going through emissions :D

That's the best idea. Here's what I would do in your situation. I'd buy an ORY (off-road Y...no cats) and some very good flowing cats like Magnaflow or Random Tech. Then take it all to an exhaust shop and have them cut the Y/bolt them in and fab up some race pipes.

Ok my next question is who can i buy a sticker from in dfw lol. Thats too much work and the exact opposite of what i wanted. My plan was to fab my own exhaust and have no cats no mufflers. I def dont want cats i want the sound.

Just seems to me that running a single cat would be restrictive and like you said ( it would have trouble reaching light off temp ) so the carbin buildup would not be getting burnt up, so the cat would be more likely to stop up.
