The downpipe i bought does not have a place for the pipe and hose from the airpump. Do I remove the airpump now...my cats were gutted before but now i am assuming I need a plate since i took off the precats and cat to put on a downpipe...

 

so you got a cat replacement (midpipe) as well as a downpipe? I assume you have a TII (sometimes people say NAs have DPs). If so, yes, get rid of your air pump.

 

Is it recommended that you get the double pulley for the alternator if you do that? I know they sell it I am just not sure why you would need it?

 

i dont have mine on, and i have yet to hear the waterpump belt slip

 

What about the temp on the gauge has it gone up any. I don't know if you can actually hear the belt slip.
