This is an exclusive S.A.S Autoworks service, being the first in the UK to carry this out. Removal of the primary catalytic converters and the fitment of a megaphone style turn down back into the exhaust has proven great power and torque gains across the entire rev range.
*All our work is completely T.I.G welded and back purged for reliability and strength.
*Please note this is a service requiring your existing manifolds to be sent to us then posted back.
*We sometimes have complete manifolds in stock and for sale keep an eye on the Shop or contact us about availability.
