Gutting Cats
Well im planning on gutting my cats because they are rattling like crazy. Whats the easiest way to get this done? Should i just gut them and leave it hollow inside or run a pipe through it. If so what size pipe would run through the original cat?

Get new cats if you don't want to risk a fine.

Gutting them is not the same as removing them. When you remove the CAT, you replace with a piece of pipe. When you do that you keep a consistant volume in your exhaust system. When you gut them, you create a low pressure spot where you loose all your exhaust velocity. Then when the exhaust has to leave the CAT it all piles up and kills flow.

I dunno that you can. If anything I guess if you gutted em and found pipe that would fit you could weld it in and be ok. Like someone said earlier, sell yours to a recycler and take the money to go get new ones. Thats the best bet, and the least hassel.
