As paul said mate a conversion is way beyond my skills with a b&q socket set so i've bought a 2nd 4AGE SR (already done) but will keep mine on the rd while its worked on.....have a check back through my thread dude, pretty sure i offered you first refusals when its up for sale, probs be with the full exhaust system i got off Toby and will need your old manifold and exhaust to chuck onto mine because i had to cut mine up for the cat! Yours still standard yea?
Wont be for a while though dude
