ya haven't installed them yet. Pacesetter LTs, ORY, thunderbolt high flow cats, and cutout. I want to to two cutouts in the ory and put the cat in the I pipe but im worried it might be to far away from headers to pass emmisions. So id like to squeeze the cutouts before the cats on the ory. Looking for pics though having trouble finding some

i was thinking that, cutouts in Y pipe and cat in the I pipe right after the Y, but i was worried about the cat being to far form the headers to get hot enough to pass the sniffer? also how will the cat being in the I pipe affect my GmmG sound and air flow? if i can id rather not hack up the $900 exhaust :/ lol

Nope, whats a tape measure?

You seem to be so knowledgeable answer this, how will moving the cat down to the I pipe affect emissions and cat-back tone?

I know a place you can shove that tape measure ******...but i don't want to have a sarcasm battle, nor any problems with LS1TECH... Thank for your positive input very helpful

One good high flow should be enough on a stock car with a proper tune. I can't speak to the tone change.

Just measure and see if you have room man. Its not that hard.

My first 95z had stock manifolds and y but i had a universal cat in the I pipe with a cat back...it sounded great and passed emmisions all day long. Go for it! Worst case senario its metal cut it and weld it again but im sure everything will be a-okay.
