| Product Description | YEAR: 2024.04~ ・The Super Turbo Muffler combines low exhaust pressure with quiet operation. The URBAN MATTE EDITION is now available, with a powerful sports sound and overwhelmingly low exhaust pressure.・The tail features a matte URBAN MATTE tail , and the silencer peeking out from the bumper has a hairline finish.・The simple yet striking URBAN MATTE EDITION emits a soft, elegant light and creates a calming atmosphere.・HKS rubber stays and a special bracket are included to suppress lateral movement of the muffler during sports driving.・Muffler shape: SSR (Super Turbo Muffler URBAN MATTE EDITION)・Main Material: S304・Tail Outer Diameter: 110 L&R・Intermediate Pipe Diameter: 74.7 → 60.5 × 2 (※1)・Nearby exhaust noise: Normal 81/ HKS 91・Regarding ground clearance when installed (※2): Number 120mm / Kit target area: Front Member ・HKS product weight: 15.7kg・The maximum output and torque values exceeded those of the original.・When measuring the output, we also measured the exhaust pressure of the muffler.* The difference became larger as the engine speed increased, confirming a significant reduction in exhaust pressure.・This improves exhaust efficiency, making this a muffler that will really show its value when further tuned!!・* Regarding the notation in the graph and table : STM: Super Turbo Muffler 31029-AT017 (this product)* Exhaust pressure is measured between the spherical flange and the middle silencer.* Because the genuine ECU uses torque-based output management, simply replacing the muffler will give the same output as the genuine product.* The graph and figures are the results of in-house measurements. They may vary depending on the vehicle and measuring equipment.・The pipe diameter immediately after the flange is φ70・After the intermediate silencer it becomes Φ65.・The silencer has a structure that distributes exhaust air to the left and right.・It consists of one piece without any divisions.・Appearance:We pay attention not only to performance but also to details.The main muffler is TIG welded and carefully finished by skilled craftsmen one by one. The products produced by our outstanding technology have a finish that combines strength and beauty.・*1: Regarding intermediate pipes,the Φ number of the intermediate pipe diameter in the muffler is the Φ number of the thickest part in the structure (excluding the shell and the outer diameter of the tail).*2: When the HKS muffler is installed, the part with the smallest clearance between the HKS muffler (all parts included in the kit) and the road surface is listed. Therefore, it may differ from the minimum ground clearance of the vehicle itself.The data is basically for vehicles with normal suspension, but please note that some data is for use in combination with low-down springs or height-adjustable suspension kits.Note: Hooks, brackets, and stays are subject to change without notice.*Exhaust volume at idling |
