The SUPER TURBO MUFFLER has the same pipe diameter as the Dual Muffler, 31014-KT001, that had been released previously. Using the latest HKS technology we had succeeded in controlling the sound and keeping the volume low. We recommend this product for those, who are equipped with a catless downpipe and who are wanting to suppress the exhaust sound as much as possible.
– Inspection Ready: Ability to maintain a sporty sound while suppressing unpleasant sounds. This is a muffler for vehicles that need to pass inspection to meet strict Japan domestic noise standards.
– Factory Exhaust Valve Compatible: Structure that allows usage of the factory valve. Sports/Normal mode can be switched as is.
