Would it be smart to remove my cat? Ive heard it restricts flow alot and you gain more horsepower when you remove it. Also ive heard that you can still pass emmisions without it.

 

You will almost certainly run into CEL probs if you just remove it. I suggest you replace it with a high flow cat like a Magna Flow. As far as HP goes, you might notice a little more pep in the throttle response, but no major HP gains. What you do to the rest of the exhaust is just as important and will give you slightly better results. But nothing major like I said in the HP department. Of course you will notice a bigger gain if your stock cat is clogged or starting to go bad.

 

pends on your state laws if you can still pass..ive removed mine,,but only temporarily as mine was bad,,and stopped up and rattling,,you can remove it,,but if i was you,,,make sure and re-insert the o2 sensors back in,,and or re-do your exhaust,,as in my case next week my set ups going to be edelbrock shrties,to an magnaflow x-pipe,,and true 2.5" piping to 2 spintech prostreets and dumped underneath...

 

yeah, i would leave it alone for now unless its bad or youre redoing the rest of the system.......deez- you better put up a vid of that, i bet its gonna sound sick, have you ever posted pics on here of your truck, dont think ive ever seeing it

 

no not yet bud..ill see what i can do..

 

where do i put the 02 sensors on the new system if i remove the cat? because there is one right before the cat and one right after.

 

You have to weld in new bungs.

 

my truck only has a pre cat sensor will it throw codes if i remove the cat?

 

you should have 2 sensors

 

Removing the cat was one of the worst things I did. I would suggest getting a hi flow cat instead.
