Exhaust and silencers in s/steel from Armours, finish is as deep chrome, they will look great when fitted, they also offer s/steel mounting bracket for £5.00 each, the silencer has pinch bolt supplied, so no clamps or clips to buy.
I've been looking for stainless wheelsDevon do some of the finest, but a bit pricey, best value is from SRM at least they're made in England as for central wheel components they're sadly not.
