ok I just ordered my power fc and I have just intake and exhaust right now but I do have a downpipe and midpipe but have not put it on yet until the power fc comes in. well my question is when I install the midpipe do I have to take off the airpump or can I run with it on? and I can't really check under my car right now until I lift it up because it's so ******* low but does the air pump have that line that goes to the main cat on the third gens? well this is my first third gen but my 3rd rx7 so im kind of new to the third gens.

 

u can keep the airpump if u like..that's how i kept mine for awhile when i had the midpipe but i recently took off the airpump because i also have a pfc. you might get a fluctuating idle when you remove the air pump...the pfc however fixes this.

 

To safely run a midpipe, you should upgrade your injectors and fuel pump.

And upgrade your intercooler!
