Ok so i have a 95ls with I/H/E no p/s and new sparks and wires, and my apexi cat back is 2.36" in diameter and it pops sometimes between shifts on daily driving , and i was wondering if i gutted the cat would it make it worse and ever since i put on my exhaust and everything else my idle has dropped like to 400 RPMs

 

HELP

 

would there be too much back pressure if i put on a cat that is gutted with a 2.36 inch exhaust

 

if you gut the cat it will be worse, the reason why it pops is because of the bottle neck of the piping. You don't like the popping?
*edit, didnt read the part about your idle, maybe its not the exhausts fault
