One of my mechanic friends was dead aginst cutting it off becouse he said the small engine with high miles needed back pressure. Is he as crazy as I thought he was?

 

It's required by law.......

 

Well if you dont need them. A lot of people run staright exhaust(no cats) It can sound cool, or can sound like crap. But if yu want to run no cats, heres some ways to do it.

goto the junkyard and find valve covers off of an older truck that have "NON-CATYLYST" on the emmisions sticker. either put them on your truck and take off the cats or if you have special covers on your engine just put them behind the seat
^ you can get away with that. If you get pulled over for no cats, show the cop the valve covers.

OR YOU COULD TRY


buy a universal fit cat (small and cheap), and beat the outta the honeycomb with a big prybar and a hammer. eventually it'll poke through, and you can wallow the honeycomb out till it all falls out

^ THIS IS ILLEGAL. You can get away with it though. You still ahve a CAT but there is nothing in it.


DONT FLAME ME FOR TELLING HIM HOW TO BEAT THE COPS, THATS JUST WHAT WE DO OUT IN THE PINES.

 

i say just keep the cat on and get a high flow cat...

that is if you decide on a new exaust system.

 

Any power gaines is what I am wondering . Cops dont give a ...round here bout cats

 

But some of us do. Please, please, please, do us a favor and try to keep our air as clean as possible!

 

chances are, you will get a boost in power without the cat, esp if it is the original its probably clogged. however, its not necessarily the cops you need to worry about but state inspections. if you dont have a cat on there chances are you wont be able to pass state inspections.

you could always hollow it out so you will pass the visual inspection, but as stated earlier, its better to just get a new cat so it will flow.

 

no state inspections and cops dont care... Will it increase power??? i need a 22r to turn 31s with 4.11 gear need all the cheap help i can get!

 

it will increase power. It might sound ricey as all get out though

 

i have no cat on my truck and it doesn't sound ricey at all. kinda purrs at a low idle t hough

 

yeah..I have a 1991 pickup(22re) and im lookin to do the same...isnt there also a chance you could burn up some of the valves?

 

Not by just removing the cat or holowing it out.
