Product Description

The HKS Super Turbo Muffler isn’t just a product—it’s a symphony of science and performance. Born from a mission to combine high exhaust efficiency, sound pressure reduction, and street legality, this exhaust system handles everything from bone-stock builds to fully tuned turbo monsters with upgraded turbines.

At its core is HKS’ original sound control technology, headlined by the innovative Slotted Tail design. Inspired by the quiet flight of an owl’s feather, the sculpted tips work to reduce frictional air vibration, effectively lowering sound output by up to 2dB. That means you get a bold, punchy tone on the outside—and a refined, frequency-tuned experience inside the cabin. Low-frequency droning? Gone. Just clean, satisfying sound whether you're accelerating hard or cruising quietly.

Crafted from S304 stainless steel and shaped into the proven SSR (Super Turbo Muffler) layout, the system optimizes flow while ensuring precise sound tuning. The wide 85-70mm center piping supports big power gains, sharper throttle response, and faster turbo spool. Meanwhile, the burned titanium tips aren't just beautiful—they're the exclamation point on your performance build.

With compatibility for valved exhaust systems, this cat-back gives you the flexibility to stay stealthy when needed and let it scream when you’re ready. Whether you're tearing up the track or hitting the streets, this system offers the best of both worlds—raw power and refined sound.
