Im going to finish off my exhaust system by getting a downpipe and decat...
i already have a milltek non-res cat back...and am looking at getting the milltek downpipe, however have heard problems with it causing the engine light to come on, i presume due to the cat being removed...any one had this problem?
Also will it provide any power gains, or will the car need to be mapped again?
Also is the noise a constant drone, or will i not notice much difference than what i have now with the cat-back?
Cheers for any help...
