you can gut the cats with a crow bar or other similar type bar. there was a thread somewhere, either here or ls1 where someone ran straight pipes and cut a cat in half (top and bottom) and welded them around the pipes the cat "look" like you suggested. had pics too.

Hmmmm, that seems like the way to go. They would have to lift the car or feel around the cat with there hands to tell if they're fake.
I'll see tomorrow if the shop thats going to remove them can cut them, if so I'll just do that idea.

To answer your first question. Yes they can tell. Depending were you live but basicaly all they have to do, and they being the cops or the person inspecting the car, is shoot the converter with a temp gun. If it is not extremly hotter then the exhaust pipe, then they know something is up with it. When it works, it gets hotter then the exhaust pipe. So yes, they can tell. But ofcourse, not all officers now this, so I would bet you would get away with it on the road. But the man that does the inspection will probly know this, and may check for it. Just go to someone you trust and know. Good luck.

For a meager 5-8hp, I would not remove the Cats anyway.

I was told with my upgraded cam (242/242 .610/.610 114 lsa is my current cam, my new one will be a 248/248 113 lsa) and the fact that I'm sending my heads out to get re-ported (because they're probably not ported to the hilt like they should be, 325-330 cfm) and since I have 436 ci, that I should pick up 15-20 RWHP with no cats.
Thats a little more info for you, do you think 15-20 RWHP is accurate?

Every shop I called told me they wouldn't do it. one of the shops told me its a $25,000 fine if a shop (licensed business) gets caught doing it. I have a friend that works at a muffler shop and he's gonna do it for me.

LOL, honestly, you are way too concerned about cops & cats. Cops could care less. I have been pulled over with my loud, lopey, catless car that smells bad enough to make your eyes water and the cops don't even mention the exhaust.
It's the emissions dept you have to find a way around
And that's not hard to do at all
But since you don't even have testing, don't worry.
PS. Just in case you didn't know, you are already in violation of federal law because you have relocated your cats when you put the LT headers on. So what's the difference? Pull 'em off if you want.
I haven't had cats on any of my performance cars since some time in 1996. NO PROBLEMS after MANY traffic stops. LOL, go on, live on the edge!!!

most cops will just pull you over for whatever infraction you've done and then will let you on your way. if your to loud it might give them a reason to pull you over but most wont unless there dicks.
if you have no emissions (lucky bitch
) then just go on your way and get the ORY. Joined: Nov 2001

Yep, even when getting pulled over for loud exhaust, they STILL don't mention anything around my area for no cats, nor do they even look or care.
They either give you a ticket for the exhaust being too loud or just let you go. Cats don't even come into the conversation....
