Modstock Catless Down-pipes (S55) (See Disclaimer)

Modstock 3" catless downpipes for the S55 engine, made in Stainless steel. By eliminating the restrictive catalytic converters in the factory down-pipes, back pressure is reduced significantly which results in faster spool, an increase in power & a more aggressive exhaust note. 

(This product removes factory fitted emissions systems and is therefore not road legal, meaning this is strictly to be purchased for use off road)
