The SPEC-L2 designation represents the second generation of HKS's Hi-Power SPEC-L tuning. Revised internal geometry for improved mid-range response and a refined sound character that is more present and defined than the SPEC-L while remaining appropriate for the street.\u003c\/p\u003e\n\u003cdiv style=\"clear: both;\"\u003e\u003cbr\u003e\u003c\/div\u003e\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\u003eSPEC-L2 muffler tuning for FA24\u003c\/li\u003e\n\u003cli\u003eBRZ ZD8 specific fitment\u003c\/li\u003e\n\u003cli\u003eSingle exit configuration\u003c\/li\u003e\n\u003cli\u003eStainless steel construction\u003c\/li\u003e\n\u003cli\u003eFitment: 2022-2023 Subaru BRZ (ZD8)\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003e\u003cstrong\u003e60.5mm Pipe, 93 dB(A), BRZ ZD8-Specific Routing\u003c\/strong\u003e\u003c\/h4\u003e\n\u003cp\u003eThe AF101 SPEC-L2 for the ZD8 BRZ uses a 60.5mm main pipe and 115mm single tip, the same pipe diameter as the BT004 SPEC-L, but with SPEC-L2 internal tuning for a higher-definition mid-range pulse. Sound level is approximately 93 dB(A) at 1m at WOT, approximately 2 dB higher than the SPEC-L. The BRZ-specific routing compensates for the ZD8 underbody geometry differences at the rear axle versus the GR86, ensuring proper hanger alignment and ground clearance throughout the exhaust path.\u003c\/p\u003e\n\u003cp\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0743\/4122\/0668\/files\/7bb8a5632c94632af3311d1a4d3cded6_3751b018-0ca6-4e94-b070-1147089b4e86.jpg?v=1772084608\" alt=\"HKS HiPower SPECL2 ZD8 Cat Back Exhaust - 2022-2023 Subaru Limited | 32016-AF101\" style=\"max-width: 100%; height: auto; display: block; margin: 20px 0;\"\u003e \u003cbr\u003e\u003c\/p\u003e\n\u003ch4\u003e\u003cstrong\u003eSPEC-L vs SPEC-L2 for the BRZ Platform\u003c\/strong\u003e\u003c\/h4\u003e\n\u003cp\u003eThe ZD8 BRZ designation is Subaru's internal chassis code for the second-generation BRZ.

A more refined, fuller sound than the factory exhaust without the shrill quality that some aftermarket exhausts add to a four-cylinder application. The BRZ's character is enhanced rather than overwhelmed.\u003c\/p\u003e\n\u003cdiv style=\"clear: both;\"\u003e\u003cbr\u003e\u003c\/div\u003e\n\u003ch4\u003e\u003cstrong\u003eThe FT Breakdown\u003c\/strong\u003e\u003c\/h4\u003e\n\u003cp\u003eFor 2022-2023 BRZ owners wanting the HKS exhaust upgrade, confirm whether you want the SPEC-L (BT004) or the SPEC-L2 (AF101) based on sound preference. The L2 is the higher-specification, more performance-oriented version. The L is the more refined, subdued option. The ZD8 underbody routing difference between the BRZ and GR86 is subtle from outside the car but significant for exhaust fitment — the BRZ rear subframe geometry positions the hanger locations and heat shielding differently than the GR86. Using the GR86 exhaust on a BRZ typically results in misaligned hangers and ground clearance issues that become apparent immediately on installation. The AF101's BRZ-specific routing avoids that.\u003c\/p\u003e\n\u003cdiv style=\"clear: both;\"\u003e\u003cbr\u003e\u003c\/div\u003e","brand":"HKS","offers":[{"title":"Default Title","offer_id":52621264781592,"sku":"HKS32016-AF101","price":552.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0998\/4514\/4856\/files\/738xa3ofqh4o_f6647a91-7054-4af2-b7f6-449663c9d08d.jpg?v=1788747637","url":"https:\/\/driveforges.com\/products\/hks-hipower-specl2-zd8-cat-back-exhaust-2022-2023-subaru-limited-32016-af101-uya2cw","provider":"Drive Forge","version":"1.0","type":"link"}
