Hi all I have a 2005 wrx. It's got a prodrive exhaust, but as far as I know not the complete ppp (still trying to find that out) , but it was at 250bhp before I remapped it, so I guess it could be the ppp, but I have no certificate to prove it.
I've changed the panel filter to a cosworth one and had it remapped and is now at 285hp. It's my daily runner, so I'm not looking to get anymore hp as I think I'm at the max for the car, but if the exhaust needed replacing what should I go for? If I was to go up to 3" would I need to remap again? Would this push the hp to high for the gearbox etc?
Many thanks
