I bought a brand newCatco 3" cat with air tube so I can pass emissions. I also have an electric airpump, how long can will the cat last without air being supplied to it, since the airpump will burn up being left on

 

Just remove it and have a piece of pipe fit in there..

 

Well I do, I have the full RB exhuast, but im talking about driving to and from the emissions place, I dont want to kill the pump by having it on too long but i dont want to kill the cat either

 

how are you gonna kill the airpump? its a mechanical pump that spins at speed directly related to engine rpms.

 

Its an electric airpump, not mechanical. And no, you wont kill it driving it to get tested by the man..

 

Isn't the electric pump designed to run all the time anyway?

 

i have a catco right now w/ my racing beat system and have driven on it for about 3k without an airpump and it still hasnt melted.

 

but will the car still pass emissions testing???
