Thread: removing emmission controls

Tweet

Just bought 1980 C10 Chevy Truck. I want to remove the emmission controls.
I'd like to do this myself. Any suggestions or resources to do it in my garage?

Sorry, against the law to remove or modify emissions controls... Unless it's replacing an item with a CARB certified part....

On top of that, it will make your engine run worse.

about the only emission equipment you cant just take off and you might gain a little tiny itsy bit of performance is the catalytic converter if it even has one....and maybe the air injection pump but the really isn't going to be putting much drag on the motor... if you removed it... you might get like 1/2 to maybe even a full 1 HP gain.. other than that... you've got to do a lot more work than that to remove emissions equipment and get performance out of it... and really it'd be easier to swap in an older non-emission controlled motor... the motor is designed to use all the emissions equipment... they changed head designs and all sorts of things to make the emissions equipment function

put a better catalittic converter on it, the newer style have no flow restriction, the old style in which your truck has, does affect flow.
