Well the exhaust questions is down to personal preference...i would have straight cut personally And drilling the air box and putting a decent panel filter in there would be better than just plonking a shitty induction kit on, but if you was to do it tidy i.e. put a relocation pipe on it to near the front bumper or put a heat shield on it, or do both of them it would be OK. Oh and did you go to that meet last night Mr muddyell??? Was speaking to NeilH and he went but not in his car...... i went to the cinema instead lol
