Example BHP gains

With the above modifications we generally see the power rise to 380-385 BHP and this is with cars that from the the GPF back still have a standard original Hyundai exhaust  system. 

An induction kit normally added to the above specifications would normally see gains reaching 390 Bhp. 

Finally with a decat front pipe and all the above parts we would normally see 400 + Bhp, the highest recorded so far has been 408 Bhp.
