I am looking to purchase a X pipe, I have a connection who will pass me for my state inspection if I get an offroad pipe. However I am leaning toward getting one with Cats and purchasing some electric cut outs. What do you guys think? And does anyone have some suggestions for which brand to go with?

 

I like the bassani x...

These guys were the first to market them (there was a fellow that claimed to have beat them to the idea but I don't know how that turned out), I had gotten a 2.5 crossover kit form them years ago for my 5.0 but ended up installing it on my brothers Nova, made a helluva difference in the way the car performed (was a 355 with a single plane and ported heads on 1-3/4 long tubes. The Nova was orginally fitted with a 3" dual exaust with no cross over and 2 chamber flows.)

 

My love my Bassani X with cats.

 

Used to run a bassani X and I liked it...Was a modular design that came with cats and race pipes which could be interchanged - although the process was extremely time consuming

Brenspeed has it for 388 here...
