When I had my Pirelli done - I was in my late 20's, full NCB, 20,000 miles per year incl business.
Stock with Elephant = £1100
Revo Stg1, Neuspeed intake, Miltek Cat-back, WALK with Greenlight = £650

I was told they are competitive because they treat you more like an enthusiast. If you spend all day polishing it, you'll be a little more careful with it and not wrap it round a tree!
