I want to add an h pipe with high flow cats if possible. Can I get one that bolts up to the stock manifolds?

Yes, the majority of aftermarket midpipes are designed to bolt up to stock manifolds. The rest are for shorty headers and long tube headers.

theres a ton of h pipes out there made for the stock manifolds...however i've only seen a couple with cats...i just got the latest catalog from latemodel restoration and theres only 1 catalytic h pipe made for stock manifolds in the whole catalog...but there are more out there

^ You can do what I did. I bought a BBK o/r h-pipe and welded in high flow cats. It's a lot cheaper than buying a new catted mid pipe.
