All depends how it's registered or year I think.
Mine was an 02 plate and wasn't exempt where as my mates 03 plate is. Same car, same engine just different year.
At first i thought you may have beem after Sam Ball DC5 (or what may have been his, as i thinks hes sold it) It also had full cage, supercharger and carbon bonnet but his was an 04 plate.
Correct. Chargers are the same, manifolds are what makes the difference.
Their was a guy on one of the facebook pages a few days ago selling a JRSC with ep3 manifold but if im not mistaken either he or another member had a brand new JRSC DC5 manifold available too.
