i was wondering what kind of modification you have to do to remove the cat? and how does it make it sound? i have a stock exhaust right now but soon to come are headers and hopefully down the road sometime an aftermarket y pipe.

 

Well,...I removed the cat on my 86 IROC and there were no difficulties. It made the exhaust sound louder and more throaty. Just cut the smog tube coming down on the passenger side of the motor, going to the front of the cat, unbolt the cat from the exhaust segment, and splice new tubing in. It was the best thing that I could have done, cheapest and only took me a few hours- Just make sure you have the pipe that will replace the cat ready. Hope this helps and I didnt forget anything-

 

would it be as benifitial just to gut the cat? it seems alot easier just to take it off and gut it and then put it back on.

 

Yeah you could do that. As a matter of fact, I did it that way on my 90 model, BUT, It doesn't sound the same as my 92. I put a pipe in the cats place on the 92. The gutted cat has a hollow sound coming from it once gutted. I didn't personally like the sound of it. The best thing to do, is to just put a piece of pipe in there like resto said. As far as modifications,......there's not any that I know of.

 

What your looking for is an "off-road pipe" I know people sell them. Not sure who though. Look around for it and you'll find it.

 

so the gutted dosent sound as deep and throaty as just the pipe.
