Hi everyone,

Got a decat up pipe for my04 wrx, what is the best way to fit it?
Manifold off or turbo off? Any how to's?

Also, have ppp ecu and full decat down pipe fitted, would an immediate remap be reqiured?

 

Anyone?

 

I don't think the ppp ecu will cope with a full decat, also you will have cel lights on that will need fixing, I think a remap would be on the cards sooner rather than later.

 

i prefer to take it out from the bottom, removing half of the headers and loosening the o/s engine mounting and jacking the engine up a little. Although ive not removed one with a cat so dont know if it will come through the gap
