The Hi-Power SPEC-L2 muffler design delivers HKS's most refined single-exit exhaust character for the platform. Improved mid-range response, defined exhaust note under load, appropriate sound level for street use.\u003c\/p\u003e\n\n\u003cdiv style=\"clear:both;\"\u003e\u003c\/div\u003e\n\n\u003ch4\u003e\u003cstrong\u003eSpecs \u0026amp; Highlights\u003c\/strong\u003e\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCat-back exhaust system\u003c\/li\u003e\n  \u003cli\u003eHi-Power SPEC-L2 muffler tuning\u003c\/li\u003e\n  \u003cli\u003eSingle exit configuration\u003c\/li\u003e\n  \u003cli\u003eStainless steel construction\u003c\/li\u003e\n  \u003cli\u003eFitment: 2013-2021 Subaru BRZ \/ Scion FR-S \/ Toyota 86\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\n\n\u003ch4\u003e\u003cstrong\u003e50.8mm Pipe, 93 dB(A), First-Generation FA20 Routing\u003c\/strong\u003e\u003c\/h4\u003e\n\n\u003cp\u003eThe AT131 single-exit SPEC-L2 for the 2013-2021 FA20 chassis uses the 50.8mm pipe diameter and 115mm tip specification of the AT123 but with revised hanger positions and mid-pipe routing optimized for the first-generation FA20 underbody layout. Sound level is identical to the AT123 at approximately 93 dB(A) at 1m at WOT. System weight is approximately 7.6 kg. Where the AT123 covers both FA20 and FA24 platforms, the AT131 is the dedicated first-generation application when a platform-specific part is required.\u003c\/p\u003e\n\n\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0743\/4122\/0668\/files\/62c7a84b738b3f34cede4b31df50e5a4L.png?v=1772080133\" alt=\"HKS Hi-Power Spec-L2 Single Exhaust - 2013-2021 Subaru BRZ \/Scion FR-S\/ Toyota 86\" style=\"max-width:100%;height:auto;display:block;margin:20px 0;\"\u003e\n\n\n\n\n\n\u003ch4\u003e\u003cstrong\u003eFA20 Dedicated Application vs the AT123 Multi-Platform SKU\u003c\/strong\u003e\u003c\/h4\u003e\n\n\u003cp\u003eThe SPEC-L2 designation represents HKS's refined evolution of the SPEC-L, with revised internal geometry for improved mid-range exhaust pulse and more consistent sound character across the RPM range.

Whether you are on the first or second generation, the SPEC-L2 provides the right balance of sound, performance improvement, and daily drivability. The AT131's platform-specific routing for the first-generation FA20 underbody is the detail that makes it worth distinguishing from the AT123 multi-platform SKU. When HKS routes an exhaust system to a specific chassis, the hanger positions, ground clearance, and heat shield proximity are calibrated for that underbody — the AT131 sits and hangs correctly on the first-generation car in a way that matters when you are driving on real roads with real speed bumps.\u003c\/p\u003e\n\n\u003cdiv style=\"clear:both;\"\u003e\u003c\/div\u003e","brand":"HKS","offers":[{"title":"Default Title","offer_id":52621066174744,"sku":"HKS32016-AT131","price":450.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0998\/4514\/4856\/files\/ha10p6azd451_76d7c6d7-d293-4224-8917-6a42d56a20c0.jpg?v=1788745154","url":"https:\/\/driveforges.com\/products\/hks-hi-power-spec-l2-single-exhaust-2013-2021-subaru-brz-scion-fr-s-toyota-86-jsgrlg","provider":"Drive Forge","version":"1.0","type":"link"}
