Nah they sound alright the ones from Halfords, lad on here stuck one on his 182, supposed to have sounded quality,also hear one on a Valver, again sounded nice... may bump the price (insurance) by 30 notes or so at a guess (dont bother telling them imo)
More expensive kits arnt any better really Karl, you pay a big price just for brand name, but i have got a thing for pipercross, but use ITG personally..
