The axle-back scope means the installation is straightforward and accessible. The factory flanges at the axle are unbolted and the HKS Legamax muffler replaces the OEM unit. The Legamax sound character is deep and refined rather than aggressive.\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\u003eAxle-back exhaust, muffler replacement only\u003c\/li\u003e\n  \u003cli\u003eRetains factory cat and front pipe\u003c\/li\u003e\n  \u003cli\u003eLegamax muffler design, deep, refined sound\u003c\/li\u003e\n  \u003cli\u003eSimple installation using OEM flange connections\u003c\/li\u003e\n  \u003cli\u003eStainless steel construction\u003c\/li\u003e\n  \u003cli\u003eFitment: 2013-2016 Scion FR-S \/ Subaru BRZ\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\n\n\u003ch4\u003e\u003cstrong\u003e50.8mm Inlet, 110mm Tip, 87-88 dB(A), 5.2 kg\u003c\/strong\u003e\u003c\/h4\u003e\n\n\u003cp\u003eThe axle-back Legamax uses a 50.8mm inlet pipe matching the factory mid-pipe diameter and a single 110mm tip. Sound level at WOT is approximately 87–88 dB(A) at 1m, roughly 3 dB over stock and the quietest HKS exhaust option for the early FA20 platform. The muffler body is 135mm diameter and 300mm in length, fitting within the factory hanger and heat shield clearances without modification. System weight is approximately 5.2 kg versus the OEM rear muffler section at approximately 6.8 kg.\u003c\/p\u003e\n\n\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0743\/4122\/0668\/products\/b68340bb2600e0338f920ccf08609e18.jpg?v=1697651631\" alt=\"HKS Legamax Axle Back Exhaust - 2013-2016 FR-S \/ BRZ\" style=\"max-width:100%;height:auto;display:block;margin:20px 0;\"\u003e\n\n\n\n\n\n\u003ch4\u003e\u003cstrong\u003eAxle-Back Scope and Legamax Sound Character\u003c\/strong\u003e\u003c\/h4\u003e\n\n\u003cp\u003eThe axle-back is the entry point to the exhaust upgrade path. It is the least invasive change. You keep the factory mid-section and just replace the muffler. For FA20 owners who want an exhaust sound improvement without the full cat-back investment, the Legamax axle-back delivers meaningful character change at lower cost.\u003c\/p\u003e\n\n\u003cdiv style=\"clear:both;\"\u003e\u003c\/div\u003e\n\n\n\n\u003ch4\u003e\u003cstrong\u003eEntry Point to HKS Exhaust on Early FR-S and BRZ\u003c\/strong\u003e\u003c\/h4\u003e\n\n\u003cp\u003eFitment covers the 2013-2016 production run, the pre-facelift FR-S and BRZ.

It installs in an afternoon with basic hand tools and the Legamax muffler character is immediately noticeable. A good starting point for the exhaust build. The 87–88 dB(A) and 5.2 kg weight saving from the Legamax axle-back is the entry-level HKS exhaust upgrade for the early FR-S and BRZ — it provides a real quality improvement over the factory muffler at a lower price point than a full cat-back and with a simpler installation. For owners who want to start somewhere on the exhaust build without committing to the full system, this is the correct starting point.\u003c\/p\u003e\n\n\u003cdiv style=\"clear:both;\"\u003e\u003c\/div\u003e","brand":"HKS","offers":[{"title":"Default Title","offer_id":52621201473816,"sku":"HKS32018-AT039","price":417.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0998\/4514\/4856\/files\/9otfllxfm3bv_21fcb0c5-f4fe-49c9-84ec-621f3de83791.jpg?v=1788746842","url":"https:\/\/driveforges.com\/products\/hks-legamax-axle-back-exhaust-2013-2016-fr-s-brz-ekhc9c","provider":"Drive Forge","version":"1.0","type":"link"}
