Maximum power through my exhaust?
 

What BHP is the exhaust on a jdm bug prosrive good for? It's not the prodrive exhaust but just has 'sti' written on it. Am hoping to have the car booked in to scoobyinic for a bigger turbo and injectors soon, don't wanna really upgrade the exhaust as I know I'll end up with a different sound

depends if it has the prodrive sports cat or standard cat on

Decat

You should be ok for high 300's if still on a 2.5 system
