Exhaust Question

[NightRoller USP]

I used to own a subaru wrx and I couldnt put an aftermarket exhaust on with out some sort of engine managment. My question is: Do I need some sort of engine managment if I put a Milltek exhaust on my car.


BTW I have a hole in my exhaust......seems like a perfect excuse to start my modding!

i'm 99.99999999% sure , engine management is not necessary.

course getting some tuning done to the engine (flash) couldn't hurt + exhaust system = more power
