The sporty sound is tuned for everyday engine speeds and can be experienced inside the cabin. Reduced exhaust back pressure compared to the Hi-Power Spec-L II promotes smoother exhaust flow.\u003c\/p\u003e \u003ch3\u003eLightweight Design Inherited from the SPEC-L:\u003c\/h3\u003e \u003cp\u003eAt just 10.2 kg, this stainless steel dual-exit exhaust system is lighter than the stock exhaust system at 16.2 kg. The thickness of the silencer shells, pipes, and other components has been optimized to minimize weight. Despite featuring large-diameter Ø110 titanium tailpipes, the Hi-Power Spec-L GT retains the lightweight design inherited from the SPEC-L, helping bring out the GR86’s naturally agile sports performance.\u003c\/p\u003e \u003ch3\u003eThin-Wall Construction:\u003c\/h3\u003e \u003cp\u003eOptimized material thickness throughout the system reduces weight while maintaining the design’s performance requirements. Main Silencer Outer Shell Thickness: t0.5 mm. Mid Silencer Outer Shell Thickness: t0.6 mm. Pipe Wall Thickness: t0.8 mm (t1.2 mm in some sections). Outer Tailpipe Wall Thickness: t1.0 mm (Titanium).\u003c\/p\u003e \u003ch3\u003eLarge-Diameter Ø110 Titanium Tailpipes:\u003c\/h3\u003e \u003cp\u003eWhile retaining the lightweight design of the SPEC-L series, the tailpipe diameter has been increased from Ø94 mm to Ø110 mm. The larger tailpipes create a bold, distinctive presence that complements the GR86’s rear styling and delivers the aggressive appearance expected of a sports exhaust system. The titanium outer covers combine weight reduction with a premium finish.\u003c\/p\u003e \u003ch3\u003e2-Way Tailpipe Finisher Adjustment:\u003c\/h3\u003e \u003cp\u003eChanging the mounting position of the tailpipe finishers allows the protrusion of the inner tailpipes to be adjusted in two stages. Style 1 positions the finishers further outward to emphasize the large-diameter Ø110 titanium tailpipes, while Style 2 provides a cleaner, more integrated appearance alongside the body. This customization feature of the SPEC-L GT allows the rear view to be tailored to individual styling preferences.\u003c\/p\u003e \u003ch3\u003eExhaust Sound:\u003c\/h3\u003e \u003cp\u003eBuilding on the sporty sound of the SPEC-L, the exhaust note has been tuned to enhance the low- and mid-frequency range at typical driving speeds. The result is a deeper, fuller sound that adds a sporty character to everyday driving. Rather than simply making the exhaust louder, the Hi-Power Spec-L GT delivers a more powerful, dynamic sound during acceleration. The exhaust note develops with rising engine speed, adding to the excitement behind the wheel. Its distinctive exhaust note and bold Ø110 titanium tailpipes make every drive more engaging.\u003c\/p\u003e \u003ch3\u003ePerformance Comparison:\u003c\/h3\u003e \u003cp\u003eFlow characteristics were evaluated using a flow bench to optimize exhaust flow and minimize back pressure. The Hi-Power Spec-L GT achieves approximately 35% lower exhaust back pressure than the factory exhaust system and approximately 4% lower than the Hi-Power Spec-L II. Its optimized internal design promotes smoother exhaust flow with reduced resistance.\u003c\/p\u003e \u003ch3\u003eSpecifications:\u003c\/h3\u003e \u003cul\u003e \u003cli\u003eCertification Number: JQR30263093 FA24\u003c\/li\u003e \u003cli\u003eMain Material: SUS304\u003c\/li\u003e \u003cli\u003eTail Tip Outer Diameter: d-110 (Dual Exit)\u003c\/li\u003e \u003cli\u003eMain Pipe Diameter: d-65⇒d-50.8×2\u003c\/li\u003e \u003cli\u003eSound Level (Stock): 82dB (At Idle: 57dB)\u003c\/li\u003e \u003cli\u003eSound Level (HKS): 90dB (At Idle: 63dB)\u003c\/li\u003e \u003cli\u003eMinimum Ground Clearance: 125 mm\u003c\/li\u003e \u003cli\u003eMeasurement Point: Mid-pipe under the rear subframe\u003c\/li\u003e \u003cli\u003eWeight: 10.2kg (Stock: 16.2kg)\u003c\/li\u003e \u003cli\u003eRemarks: Minimum ground clearance remains unchanged.\u003c\/li\u003e \u003c\/ul\u003e ","brand":"HKS","offers":[{"title":"Default Title","offer_id":60823655645470,"sku":"32016-AT132","price":9298.8,"currency_code":"AED","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0784\/0553\/3982\/files\/hks-32016-at132-exhaust-system-7.jpg?v=1793867643","url":"https:\/\/atomic-shop.ae\/products\/hks-32016-at132-exhaust-system-spec-l-gt-for-subaru-brz-zd8-toyota-gr86-zn8","provider":"ATOMIC-SHOP Performance Parts \u0026 Motorsport Equipment - UAE","version":"1.0","type":"link"}
