Designed specifically to slip over factory 1.72-inch to 1.75-inch outer diameter (OD) header pipes, it eliminates unnecessary weight while maintaining thermal durability against exhaust discoloration. The integrated, removable Shorty GP catalyst baffle (dB killer) controls acoustic resonance to approximately 95 dB, preventing low-end scavenge loss without inducing turbulent flow reversion.\u003c\/p\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;\"\u003e1995-2017 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;\"\u003eTwin Cam \/ Evolution (80-103ci) \/ 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;\"\u003e68 hp \/ 82 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 (Slip-on Upgrade)\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\u003e1995-2017 Harley Davidson Dyna (FXD, FXDB Street Bob, FXDL Low Rider, FXDWG Wide Glide, FXDC Super Glide Custom, FXDF Fat Bob)\u003c\/li\u003e\n  \u003cli\u003eFits factory header pipes with 1.72\" to 1.75\" outer diameter\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003ch4\u003eDoes this fit the FXD Dyna?\u003c\/h4\u003e\n\u003cp\u003eYes, this is a direct fit for the 1995-2017 Harley Davidson Dyna equipped with the \u003cstrong\u003eTwin Cam\u003c\/strong\u003e or \u003cstrong\u003eEvolution\u003c\/strong\u003e engine utilizing 1.72\" to 1.75\" OD headers.\u003c\/p\u003e\n\n\u003ch4\u003eIs an ECU recalibration or carburetor re-jetting required after installation?\u003c\/h4\u003e\n\u003cp\u003eWhile the internal baffles retain sufficient backpressure to run safely on stock mapping, ECU tuning or carburetor re-jetting is recommended to optimize the air-fuel ratio and maximize torque gains.\u003c\/p\u003e\n\n\u003ch3\u003eThe Harley Davidson Muscle Standard\u003c\/h3\u003e\n\u003cp\u003eBuilt to handle extreme exhaust gas temperatures without structural fatigue, this polished stainless steel system delivers aggressive acoustic presence and clean mechanical aesthetics for authentic American V-twin power.\u003c\/p\u003e","brand":"VelocityMax","offers":[{"title":"Default Title","offer_id":67531034755320,"sku":"DS-E3HGWD4ZZ","price":145.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0800\/1290\/2648\/files\/slip-on-exhaust-tips-for-harley-davidson-dyna-1995-2017-stainless-with-baffle-1.jpg?v=1790528307","url":"https:\/\/performancechiptuning.com\/fr\/products\/slip-on-exhaust-tips-for-harley-davidson-dyna-1995-2017-stainless-with-baffle","provider":"Performance Chip Tuning","version":"1.0","type":"link"}
