Go to JKM, portsmouth, miltek dealers, for Res system fitted will be around £450 inc vat. Give Kate a ring and said Phil Mc sent you, and see what she quotes you, alot less then figures posted above. Top service from those guys. Very highly recommended02392 639933i have just bought a cat back milltek for my ed30 fitted it was £422. that was for a non res catback system. That inhances the soundtrack and looks, has made a marginal improovement to the accelaration and next to nothing on bhp. If you want more bhp, you will have to pay nearly £1000 and include a Downpipe and sports Cat for around 15bhp increase at best..Remap will gain you approx 30bhp, with full exhaust expect 245 approx.
