I believe they're all Cali spec from 2001 onwards. My 2000 is Fed spec.

 

They ALL have the main catalyst after the y....thought I didn't need to specify that part

 

Some noobs dont know and dont one of them have it built into the Y pipe?

 

right...like I said. Cali spec 00/01 had one precat in the Y, one precat attached to the manifolds, and one MAIN cat behind the Y. FED spec 00 and 01 had both precats in the Y and one MAIN cat behind the Y.

edit - just checked and 02/03 had both precats attached to the manifolds, and NOT in the Y. But still the MAIN cat behind the Y.

The exhaust after the Y pipe is the exact same from the 2000-2003, except the minor muffler differences. Everything fits between them (compatability)

The only difference is the Exhaust manifolds and Y pipe arrangement.

 

I tried really hard to hold this back, but between the guy saying he's never heard of a supercharged 3.0 and the OP's terrible spelling and grammar, I have to say something.

I can't believe how many positive responses/attention at all, this thread has received.
Especially from tuner, I've seen you tear other threads/posts up for far less haha.

I'd be surprised to see proof of this noob/idiot doing even half of what he says he's going to do. How many y-pipes are you putting on your car man?
