HKS Super Turbo Catback (RZ34)

Key Features:

Achieves approximately 40% reduction in exhaust resistance compared to stock with a dedicated full dual layout.

Dedicated φ60.5×2 Full Dual Layout:

By adopting a full dual layout with φ60.5×2 compared to the stock pipe size of φ45×2, it maintains a low minimum ground clearance variation typical of high-performance mufflers and secures a pipe cross-sectional area equivalent to φ85. This results in about a 40% reduction in exhaust resistance compared to stock.

Balancing Comfort and Sportiness in the Steady State Range:

Optimizing the silencer structure and using a silent chamber eliminates unpleasant resonance noise in the steady state range while still allowing you to enjoy a sporty sound characteristic of a high-power V6 engine when you step on the gas.

About HKS Mufflers:

※1: About Intermediate Pipe

The number of φ in the intermediate pipe diameter in the muffler is the largest diameter part in the configuration (excluding the shell and tail outer diameter).

※2: When installing an HKS muffler, we specify the clearance between the HKS muffler (all parts included in the kit) and the road surface at the point where it is the smallest. Therefore, it may differ from the overall ground clearance of the vehicle.

The data is primarily for normal suspension vehicles, but there is also data for use with some lowered springs and height-adjustable suspension kits. Please note this in advance.

Note: Hook, bracket, and stay may be subject to change without notice.
