Where to get Catted H-Pipe for Longtubes?

[bryan0]

I have an o/r prochamber with mac longtubes and I'd really like to toss the o/r and buy a catted h-pipe. I've searched the world over for a catted l/t prochamber, but couldn't find one. Does anyone know where to get one or any other catted l/t H?

Thanks

Yea America Muscle (grumble grumble) has them, here: http://www.americanmuscle.com/bbk-hpipe-shorty-catted-9604.html

edit: make sure they fit your mac lt's though, not sure if there would be fitment issues or not
