that is a good thought. I wonder if i split the cat in half and weld a 2.5 in pipe through it so when i put it back it is a straight pipe with a cat around it. I cant get a sticker wo one

 

That should work, you must have emissions there?

 

nope no emissions yet but there has to be a converter and if it rattles it fails so i need to fix mine one way or anouther
thanx for all your help guys

 

When you guys say your cats bolt up to your exhaust do you mean the bolts where it links up to the exhaust manifold? Because those are the only bolts I could find on my whole exhaust. My exhaust is stock untill about 3 feet past the cat where my Flowmaster and turndowns are. I didn't know if yall had bolts on the cat itself or what.

 

My factory cat was welded on. If you get a new one just get one you can put on with clamps like your muffler.

 

My muffler is welded on. As a matter of fact my cat-back is completely welded. Even the hangers are welded to the frame. They built it to stay I guess. I wish I could just take the cat off, pry it open, clean it out, and just put it back in place. The only way to get mine off is to cut it off. The cat is also a two in one out design. It would be difficult for me to weld that back up since the rest of the exhaust would have to stay on the truck.

 

I was planing on doing this to my truck this weekend but ill have to do it a later date now. I have to mave my ex girlfirend...the disatvantage to having a truck. lol I will keep you informed as to how it works for me. Where can i buy the trick o2 sensor?

 

i just did this to mine a few weeks ago, cut it open hollowed it out and rewelded it back up, sounds great gives a noticible power increase and has not thrown a CEL on my truck.

 

here are a few sound clips as well.
this one is of the exhaust close up, like right nerar the pipe.

i chose to gut the cat over getting a whole load *** exhaust system because i plow snow and dont want/need a load *** exhaust, this gave it a nice sound, thats not too loud.

 

Goldpro, what kind of muffler is on your truck and do you have a 318 or 360?
I'm trying to use your sound clips as a reference to see what mine would sound like with a gutted cat.
