Like the title says. Just scrape them out with a crowbar? Cut open and weld them back together?

 

Crowbar or long screwdriver with a hammer.

 

Take it/them to a TAXIDERMIST.

 

I would have to agree.....

 

if for sound is one thing, but i know you bought your ls1 for speed and gutting the cats actually affects performance a bit...

take it to a muffler shop, say its going to be a drag car and tell them to replace the cats with straight pipe, sell the stock cats for 150$ to a guy on that buys used/new....

both of two worlds!

 

I gotta pass a visual inspection every year. I was under the impression I would pick up a few ponie gutting cats?? I have a friend who welds so should I cut them open and have him weld in a pipe?

 

gutting the cats messes up the flow direction...bounces around instead of flowing straight though.

yea id have a buddy put straight pipe through the middle.

 

agreed, sell the cats and get a ory or something else

 

long *** drill bit or a long screw driver and hammer..anything thats long enough basically ram it through the cat a bunch of times untill all the ***** out

 

yeah i would try to sell the cats if you can, cause their worth alot.

 

either put in straight pipes or leave them on. It's not really worth the trouble gutting them. They dont rob that much hp unless you're making alot

 

Buy an ORY first. Then take and cut the cats off the old pipe, take just the shell off and weld it around the ORY. That way it is really flowing through an ORY but appears there are funtioning cats. That's what I did on my other car and it worked like a charm!
