emissions coming up
should I just buy a nice hi-flow cat or pay someone to pass it? if I get the cat then it will pass there after but paying someone will be a yearly thing.
also with my mods what high flow cat will be garanteed to pass. I still have my egr and air and all of that. just no cat with my LT's and ORY.

go with the catted y. finding someone that is willing to pass you is extremely difficult. i speak from experience. i have read that even people with strong h/c combos pass emissions by swapping out injectors and leaning everything out. also i dont think you can put a cat at the end of the y unless yours is a lot shorter than mine (kooks). the cat will hit the driveshaft.

Well, I purposely added cats to my car for emmissions. I have shorty headers with highflows in the y-pipe in pretty much the same location as stock. I'm considering getting LT's and just swapping in the shorties and catted y for testing which is a big pain in the ***.

a single catted y should be adequate. I have a single cat, granted it's stock and huge, but it has been good enough to pass the sniffer here in Ca all the while being at the end of the y. I'd imagine Texas has a more forgiving requirement.

What I did to my car was I took it to a local muffler shop and got them to flange the cat. so it only has to be hooked up once a year for inspection and then I keep it straight thru pipe. It's not to much louder at idle but when you get on the gas then dang. My car picked about a tenth and it only cost $100.

I got the magnaflow cat with a flange welded on for quick removal. Unfortunately, with my combo, I still failed...barely. Leaning it out only made matters worse, perhaps I was a little too lean.

yea i wanted to do the flanged cat and straight pipe but the shops I went to seemed like they didnt understand or couldnt do what I was asking. would a local muffler shop do it? i mean is it legal for them to do it? and here in college station they dont have a sniffer test but im not sure if they look for the cat or not.
but in the case I have to go to houston and get sniffer'ed a single cat on the y would work?
