Dreamscience De cat pipe
3 inch De Cat in stainless steel for Focus ST225
Not legal for road use in the UK.
The dreamscience De Cat is a 3″ cat replacement pipe, this direct replacement is extremely unrestrictive and free flowing as you”d expect from a de-cat pipe. This is supplied with 4 new fitting bolts which will be needed as the std ones generally rust solid and snap when removed.
This particular replacement will make the biggest difference in perfomance when changed as it is the most restrictive part in the standard exhaust system.
