Like the F8x before it with the S55, the S58 in the current generation leaves a lot to be desired. While a step in the right direction from its forerunner the stock vocals still carry far too much rasp that do not fully articulate the refined aggressiveness typical of the brands signature performance models. Dinan corrects this weakness with a valved axle back exhaust system that elevates the tone to a deeper, more meaningful note while also delivering an extra level of amplification above and beyond its stock counterpart. Coupled with the optional middle exhaust \/ x-pipe for the platform an even louder, smoother, and fuller soundtrack is possible.\u003c\/p\u003e\u003cp\u003e\u003cb\u003eFeatures:\u003c\/b\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eMaximum gains of +6 HP and +5 lb-ft of torque\u003c\/li\u003e\n\u003cli\u003eEnjoyably louder, sportier sound\u003c\/li\u003e\n\u003cli\u003eDrone abatement technologies used to reduce cabin resonance\u003c\/li\u003e\n\u003cli\u003eFour, diffuser filling, 4.5-inch (114mm) double-walled, polished stainless steel clamp-on tips with laser engraved Dinan logo\u003c\/li\u003e\n\u003cli\u003eLarger diameter piping for increased flow (76mm vs. 70mm)\u003c\/li\u003e\n\u003cli\u003e6-pounds lighter than the stock axle back (Stock: 44-pounds vs. Dinan: 38-pounds)\u003c\/li\u003e\n\u003cli\u003eStock exhaust valve actuators reused, and operation of exhaust valve is unchanged so exhaust tone can be adjusted via the M-drive settings\u003c\/li\u003e\n\u003cli\u003eComputer controlled exhaust valves are retained and limit noise during low-speed driving and open fully during high-load conditions\u003c\/li\u003e\n\u003cli\u003e100% 304 Stainless Steel construction\u003c\/li\u003e\n\u003cli\u003eFactory-like fitment with included mounting hardware\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003eStainless Steel - Polished Tips - G80\/G82\/G83\u003c\/p\u003e","brand":"Dinan","offers":[{"title":"Default Title","offer_id":51827681493304,"sku":"D00G D660-0093","price":2710.5,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/11000091.webp?v=1778811406","url":"https:\/\/store.motormia.co\/products\/freeflow-exhaust-g8x-m3-m4","provider":"MOTORMIA","version":"1.0","type":"link"}
