One is bolted to the exhaust manifold the other welded to the y-pipe.You will have to replace them w/ a off-road y-pipe or headers w/ off-road y-pipe. Mac has a off road y-pipe or Pacesetter headers w/ off road y-pipe.

so IMO taking off the cats really help out a ton. In my opinion the cat delete was more noticeable than lid.

actually it does, when i raced my brothers ws6 in my z28, all i had on him was cat delete, lid, stock exhaust piping all the way to an 80 series... he was bone stock. i pulled him pretty hard prob 2-3 cars... i also have the vid to prove it.

That is nothing more than drivers. Just taking the cats off and not changing anything else doesn't fix the restriction problem in the exhaust. There have been cars that have lost HP from taking off there cats, and there are cars that have gained 5-10hp but 5-10 hp isnt going to be noticble. I have played around with different set ups on the Dyno, I put cats back on my GMMG cause it sounds like *** without them. WIth LT's cat's and GMMG I only gave up 4hp by putting them back on, but the sound was so much better.

You need to get rid of that 80's series one of the worst flowing mufflers for our cars, and they sound like crap too...

i have lts and a cut-out before the 80 series... so i dont need to take it off.
