Dependant on what 460 you have, you will struggle to find many systems for the 400 series (480 seems easier) ^ Might do a system (need to phone them) ^ will make a custom build stainless system for you, but will cost more than the 460 is worth! My advise :- Stick to a stock silencer, just not worth the cost and agro, unless it's a turbo, then maybe?
