i got a 83 z28, and my cat is almost shot on it, the air pump is going out too. so instead of spending mass cash i just want to take it off, would this hurt anything or just help out by having better airflow? also, do i have to weld an exhuast piece in place of the cat, or is there a exhaust connector that doesnt need welding? thanks!

 

Hey man! Welcome to the board. If I'm not mistaken somehow you can just shove a pipe through the cat then bolt it back on. Hopefully someone else will chime in.

Check and see if your cat is bolted on. If so, just unbolt it, use a prybar to gut it and then just bolt it back up.

 

if youre planning on doing that i really hope you dont have to pass an emissions test

 

thanks alot guys!

it is a bolt on so ill take that off later and gut, and no, luckly i dont have to pass an emissions test!

 

i officially dont like you....the ability to tear out my cats/AIR/egr is just a dream for me since i live in canada.
