what diameter of rod should i use to rod out my CC?

 

[Snoranger]

You shouldnt.


Its against the forum rules to discuss such things here.

You should just get a high flow cat if you really feel like messing with the cat. Its not near as restrictive as your probably thinking

Sent from the think n' stink.

Not only is it against forum policy, but it is also a violation of federal law.

Not to mention that the ONLY possible way you MIGHT see a performance gain is if your cat is well and truely plugged up. You're far better off leaving it alone or buying a new cat. Modern engines rely on the backpressure created by one. This is a subject that has been beat to death.

TRS members speak truth......

Hi-Flow cat......

that way......your engine won't guzzle fuel because of a cat with no guts---

been there........

Just a good 12 gauge slug should do the trick. Gutting is a big NO-NO.

DO IT!!! your truck will rev a lot better and it makes your exhaust louder. and your gas mileage wont go down, if anything it goes up

haha nice sorry didnt know it was against forum policy. i took it off anyhow and it was clean as a whistle my fuel system is fine so im thinkin the boggin down on acceleration is in the ignition somewhere

At the scrap yard i go to they give $40 for a used cat that isnt hollow, i dont know why anyone would hollow out their cat when they could get money for it.

Which is where I would have started my search for a bogging down issue....

While on the subject of catylitic converters, I got a question. How do you tell if you have a bad one?

Do they usualy have a service life? I'm approaching 200K my 99. This was my first vehicle with converters so I haven't really delt with them in the past.

Hey guys... Remember it isn't illegal for all of us to remove or hollow out the cat. I was looking at that piece of rust called an exhaust pipe on mine a couple of months back and remember thinking that I have about 15 feet of roughly 2 inch stainless left over from a bannister project in an office building that could be bent into a sweet looking stainless tailpipe. Then I hit the search and started reading about the how the truck would react without the cat. Well needless to say after reading a few posts I still have 15 feet of unbent SS pipe and a piece of rust from the muffler back.

Now at the risk of sounding stupid... I just looked on ebay at stainless cats. Right off my Y pipe is a cylindrical unit that I think is the muffler but it looks like some of the stainless cats. What I was presuming was the cat is a more rectangular looking thing just before the axle bend in the tail pipe. HMMMM... which is which? Maybe stainless exhaust will happen if I have them backwards. You can tell I am an old timer because cats were not cylindrical and for the last several years I have had diesels which don't use them.
