Description
The HKS Hi-Power Spec R mufflers are designed for no compromises whilst still maintaining a reasonable noise level for street use. In the pursuit of absolute efficiency, a one piece design was utilized and titanium was chosen as the preferred material due to its incredible lightweight properties and durability against the weathering and long term use.
Hi-Power Spec R mufflers are on average 65% lighter than the manufacturer’s standard muffler system and the single piece design reduces the inefficiencies that can be found at joints whilst allowing for the straightest possible design.
