Product Description

The heavy, restricted factory exhaust is completely strangling the true potential and sound of your boxer engine. HKS completely flips the script with this aggressive, single right-side exit bullet-style muffler system, engineering a massive upgrade that trades boring stock aesthetics for undeniable race-inspired street presence. By upgrading from the restrictive 60mm stock pipes to a massive 85mm main pipe featuring a straight-through silencer design, this system drastically reduces backpressure. This translates to an incredibly noticeable punch in mid-range responsiveness and a furious top-end pull that will keep you glued to the seat between 5000 and 6000 RPM. Furthermore, swapping out the clunky factory quad-exit setup for this streamlined single-exit sheds nearly 9 kilograms of dead weight, fundamentally transforming how the chassis handles tight corners and rapid acceleration. The adjustable tail tip even lets you dial in the exact protrusion length, guaranteeing a perfectly flush, custom fit that looks right at home at any car show.

Upgrading to a premium exhaust shouldn't force a choice between a civilized daily commute and an obnoxious track day weapon. Because this system includes a brilliantly designed removable inner silencer, drivers maintain total control over their vehicle's acoustic footprint—running a pleasant, tuned 88dB on the street, or pulling the silencer to unleash a ferocious 100dB roar that perfectly amplifies the engine's heartbeat. You absolutely need this exhaust because keeping the factory piping is quite literally leaving free horsepower, sharper handling, and an intoxicating soundtrack locked away. For decades, HKS has been the undisputed pioneer of Japanese aftermarket performance, relentlessly testing and developing motorsport-grade components that never compromise on quality or fitment. Stop settling for a quiet, heavy, and uninspired daily driver; bolt on this legendary HKS single-exit exhaust system and give your vehicle the dramatic weight reduction, explosive power, and unmistakable sound it desperately craves.
