I am new to the mazda world and am replacing my exhaust system with a catback system and know that I need to block off the split air pipe. When I proceed and do this do I need to also remove my air pump and Air control unit or can I just block off the split air pipe outlet?

What year rx?

Rx7 Turbo II 87

this post should be in the 2nd generation section.

Sorry new to this and haven't figured out where everything is located and should be posted. Sorry...

if you replace your cat-back you don't have to touch the ac&cv, that only gets effected when you install a header really. oh and this is a turbo car, hummm yeah you still don't have to touch the ac&cv with cat-back.

Only take out the air pump and ACV if you are removing the CATS for good. Dont' do it if you are just replacing the cat back system.

I was thinking of removing the cats all together and just leaving a catback system without any cats. I do not plan on putting on the cats again. I was informed that I will need to block of the split air outlet. In doing so will this cause damage if I leave the Airpump and air control unints installed or do I need to remove them? What benifit would I receive in removing them?

it simplifies the engine bay, loses some weight, and makes your car stinky.

why stinky?
