Hi,
I need some advice. I have a 56 plate STI 2.5 without the PPP. I want to modify it a bit for some more BHP and to sound better. Thinking of getting a new back box, cold air induction kit and maybe a HKS dump valve.
Been looking at Blitz and DC back boxes and various induction kits and wondered if anyone had any advice on whats best to buy???
Thanks for your help!
