but i dont want a decat because that just pisses about when coming to have MOT DONE u know what i mean.
so CAT BACK OR BACK BOX????
and POWERFLOW (CUSTOM) or ?????????
thanks guys
IMO if u gona do it i wud go for the full catback as u wont get any gains from just back box. Im not sure how gud the std st170 catback system is as the car is a tuned up 2.0, so if its sound maybe just remove a silencer. I know the manifold and cat are good as the cat is a sports cat and is gud upgrade on 1.8/2.0.
If you decated, it wud be easy enuf swap cat over as its seperate from manifold, but sum people do report loss in bhp with decat.
Sum1 may cum along and correct me, but this is from wot i seen from m8s cars and what iv read
