1995 5.0 - adding CatBak
Ok... just got my CatBak system in from Summit and ready to put on this weekend. I got under there and there appears to be two cats, or either it's one cat and a 'resonator' downstream from the first cat. I'm searched and read the other threads but am still uncertain. My CatBak has a 1 into two muffler then dual pipes run out the back.
Should I take the second cat/resonator off or leave it on? From what I've read I'm not so sure it would matter much at all. I want it with a nice low rumble, and getting loud when I stomp on it, but I don't want it obnoxiously loud. It's a stock truck engine / exhaust except for the K&N FilterCharger I added to it.
Also.... how do I know IF my cats and/or resonator is clogged up and needs replacing!?!?! Might as well do it while I'm here if it needs it. And what does a "resonator" do anyway? I understand the function of two cats with the air input between them, etc.... but if it isn't two cats and that last hunk is a resonator.... what's THAT do?
Thanks guys!!!

I would def take the second cat out....DEPENDING ON WHERE YOU LIVE and wether you have to pass SMOG. How many miles are on your motor/exhaust and has your cats ever been changed? I think I had to do mine inbetween the 90-100K mark. If your rackin up the miles on your motor most likely they are close to clogged and it will go soon anyway. So I would swap it out for a high perf one. It will def complement your new exhaust....even if its just a normal (unclogged) cat.

Well... maybe I'll just wait to put it on until I can buy me a new cat then. 
As far as I know and it looks under there, it's all OEM. My truck has 164k on it. <huge grin> and still runs like a top. Just replaced the Wires and Plugs, Distributor cap and rotor today just for the helluvit. Wasn't running bad, but I can tell an improvement afterwards.
Crappit. Guess I'll Have to get a cat and then have a new y-pipe put on, etc... maybe they have those at Summit. I'll look.

Ok you gurus.... what do I do now? I'm getting depressed. Is there somewhere I can order a BOLT ON y-pipe and cat so I can hook my catbak system up? Or even a y-pipe with a straight pipe comin around so I can hook it up? Am I screwed?.... needing now to just punt and order a full system?
Maybe I can cut a hole in the side and get all that honeycomb crap out and then weld it back. hehehe
