The zero-baffle architecture optimizes exhaust evacuation, while a high-temperature black powder coat rated to 1400°F prevents oxidation under severe thermal cycling. Pre-installed fiberglass exhaust wrap insulates radiant header heat, safeguarding rider ergonomics and keeping exhaust gas temperatures high for improved scavenging velocity.\u003c\/p\u003e\n\n\u003ch3\u003eWhat's Included\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e2 Drag Exhaust Pipes (heat wrapped)\u003c\/li\u003e\n  \u003cli\u003e2 Exhaust Flanges with Retaining Rings\u003c\/li\u003e\n  \u003cli\u003ePipe Interlock Bracket and Mounting Hardware\u003c\/li\u003e\n  \u003cli\u003eStainless Steel Wrap Ties\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eTechnical Specifications\u003c\/h3\u003e\n\u003cdiv style=\"overflow-x: auto; margin-bottom: 20px;\"\u003e\n  \u003ctable width=\"100%\" style=\"border-collapse: collapse; border: 1px solid #e0e0e0; font-size: 14px; min-width: 300px;\"\u003e\n    \u003ctr style=\"background-color: #f9f9f9;\"\u003e\n\u003cth style=\"padding:10px; text-align: left; border: 1px solid #e0e0e0;\"\u003eFitment\u003c\/th\u003e\n\u003ctd style=\"padding:10px; border: 1px solid #e0e0e0;\"\u003e1991-2017 Harley Davidson Dyna\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003cth style=\"padding:10px; text-align: left; border: 1px solid #e0e0e0;\"\u003eEngine \/ Chassis\u003c\/th\u003e\n\u003ctd style=\"padding:10px; border: 1px solid #e0e0e0;\"\u003eEvolution \u0026amp; Twin Cam \/ FXD\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr style=\"background-color: #f9f9f9;\"\u003e\n\u003cth style=\"padding:10px; text-align: left; border: 1px solid #e0e0e0;\"\u003eStock Output\u003c\/th\u003e\n\u003ctd style=\"padding:10px; border: 1px solid #e0e0e0;\"\u003e55-78 hp \/ 72-98 lb-ft\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003cth style=\"padding:10px; text-align: left; border: 1px solid #e0e0e0;\"\u003eReplaces OEM Part #\u003c\/th\u003e\n\u003ctd style=\"padding:10px; border: 1px solid #e0e0e0;\"\u003eN\/A\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003c\/table\u003e\n\u003c\/div\u003e\n\n\u003ch3\u003eCompatibility\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e1991-2017 Harley Davidson Dyna models with forward controls\u003c\/li\u003e\n  \u003cli\u003eFits Dyna Wide Glide (FXDWG), Low Rider (FXDL), Super Glide (FXD), Street Bob (FXDB), and Fat Bob (FXDF) with forward foot controls\u003c\/li\u003e\n  \u003cli\u003eDoes not fit mid-control Dyna configurations\u003c\/li\u003e\n  \u003cli\u003eDoes not fit 1957-1985 Ironhead Sportster models\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eFrequently Asked Questions \u0026amp; Fitment Warnings\u003c\/h3\u003e\n\u003ch4\u003eDoes this fit the FXD Dyna?\u003c\/h4\u003e\n\u003cp\u003eYes, this is a direct fit for the 1991-2017 Harley Davidson Dyna equipped with the \u003cstrong\u003eEvolution\u003c\/strong\u003e and \u003cstrong\u003eTwin Cam\u003c\/strong\u003e engines. \u003cstrong\u003eThis system requires forward controls and will not fit mid-control bikes or 1957-1985 Ironhead engines.\u003c\/strong\u003e\u003c\/p\u003e\n\n\u003ch4\u003eDo I need to tune my motorcycle after installing these pipes?\u003c\/h4\u003e\n\u003cp\u003eYes, transitioning to unbaffled straight pipes substantially leans out air-fuel ratios, requiring carburetor re-jetting or an EFI recalibration to avoid lean misfires and exhaust valve damage.\u003c\/p\u003e\n\n\u003ch3\u003eThe Harley Davidson V-Twin Caliber\u003c\/h3\u003e\n\u003cp\u003eConstructed to handle the aggressive vibration and torque pulses of large-displacement V-Twin motors, these drag pipes eliminate OEM backpressure while delivering the deep, open sound profile demanded by custom Dyna builds.\u003c\/p\u003e","brand":"VelocityMax","offers":[{"title":"Default Title","offer_id":67599144780024,"sku":"DS-E3LGZTKR5","price":127.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0800\/1290\/2648\/files\/drag-exhaust-pipes-for-harley-davidson-dyna-1991-2017-forward-controls-1.jpg?v=1791474824","url":"https:\/\/performancechiptuning.com\/de\/products\/drag-exhaust-pipes-for-harley-davidson-dyna-1991-2017-forward-controls","provider":"Performance Chip Tuning","version":"1.0","type":"link"}
