I made pretty good performance through Macs, but there are longtubes with cats. FLP and I believe Kooks comes to mind first. Don't know about Seattle but in OR an ODB1 car just has to pass a sniffer I had Macs and a Mac cat on mine and it passed fine with a Hot cam, ported heads etc etc.
If you move to Cali its different. Cool thing about OR its once every two years, doing a header swap every too years wouldn't be a big deal if for some reason it didn't pass.

i have some kooks for sale, and yes they do provide a y-pipe with cats in them. You can get the catted y-pipe from Byunspeed.com or from Scroggins Dickey for good price. If you're interested in the headers, they're 1 7/8ths stainless kooks and they are brand new for $780 shipped to you.

oh and one more thing i forgot, why can't i use a cat with long tubes? because if it that the stock cat is too long, that is not a problem, i have a magnaflow cat on there which is about 6-8 inches shorter.

I have LT's, true dual exhaust and 2 Magnaflow cats and am in no danger in WA of getting in trouble to the best of my knowledge.
** Of course this doesn't apply to malfunctioning cats or if they have more then either 50k or 90k on them......I forget which.
