alright, so I've got a 91 na. My main cat has been cut off. I've ordered racing beat headers (single outlet), presilencer, and all neccessary gaskets and flanges.

My question is, can I stop using that air pipe that previously to run from my cat? I had ut welded into the replacement pipefor the cat. but with this new setup, can I just eliminate it?

Also, would I be fine with one of the stock mufflers?

One more; Do I need to order some tubing or just use what the muffler shop has got?

p.s. I already searched, and hate to sound newbish. But I need a little help. Thanks.

That pipe is for your cat (if installed). If your deleting your cat, then delete the ACV, that pipe, and the air pump (dont forget an AVC blockoff).

if you redo your exhaust.......and remove the bung for the air pump........and get a high-flo cat......and then take out your air pump.......will you still pass MD emissions??
