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 tourqe 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 a complete pair of manifolds with the primary cat already removed
