This 3″ downpipe is the best value modification available. By eliminating the restrictive catalytic converter in the factory downpipe, back pressure is reduced significantly which results in a faster spool, an increase in power & a more aggressive exhaust note.

Off-road / motorsport use only. This part removes or alters emissions-control equipment. It is not legal for use on public roads in the UK and a vehicle fitted with it will fail its MOT. Sold strictly for off-road and competition use.
