Someone please tell me how,,, i have an 1985 z 28 camaro, i need to know soon because my cat is either going or im gettin a high flow one. I think want to hollow it for now so it sounds good and is a little more throaty i dunno.. help me out on how to do it and what to do with whatever i take out thanks

 

Take it off, get long screwdriver, and pound the crap out of it. Be sure to get everything out.

 

or use a jack handle, long pipe, cut down broom handle you get the idea and pound it to death.
