I have a 53plate wrx with ppp, looking to get a ninja downpipe with hi flow cat, will i need to get it remapped, if so will i need a highflow fuelpump?
Many Thanks

 

You would need a remap if taking a Newage WRX from catted downpipe to sportscat.

However, doesn't yours already have a Prodrive hi-flow cat ?

 

hello mate, i maybe wrong but i think on the ppp package they remove the cat in the centre section and they leave the standard downpipe with the standard cat in it, from past experience on my p1 they really choke the car.
