When flat-out performance, weight reduction, and premium construction are your top priorities, the Factory 4.1 series is the ultimate upgrade for your machine. Relied on by championship-winning factory race teams across the globe, this exhaust system replaces your heavy, restrictive stock muffler with a track-tested racing weapon designed to optimize horsepower and torque across the entire RPM range—giving you the extra pull needed to dominate sand dunes, trail loops, and racing circuits alike.\u003c\/p\u003e\n\u003cp\u003eThis premium slip-on muffler features a lightweight raw titanium canister body that sheds massive pounds compared to original equipment, significantly improving your quad's power-to-weight ratio and handling agility. The mid-pipe, structural core, and signature Euro-style end cap are constructed from heavy-duty stainless steel to ensure rugged impact durability and long-term resistance to extreme exhaust heat. Engineered with a multi-stage internal packing configuration, this oval muffler boosts exhaust gas scavenging velocity to optimize power delivery. It offers versatile configuration options, providing a direct drop-in fit with your original stock head pipe, as well as a perfect match for upgrading to an FMF Powerbomb or Megabomb header down the road. Furthermore, the modular end-cap design accepts optional FMF quiet inserts and USFS-approved spark arrestor screens to easily comply with local trail noise and forestry regulations.\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cb\u003eFactory Level Performance:\u003c\/b\u003e Engineered to deliver substantial horsepower and torque gains across the bottom, mid, and top-end pull.\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eRaw Titanium Body:\u003c\/b\u003e Ultra-lightweight titanium canister construction dramatically reduces overall machine weight compared to the bulky stock exhaust.\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eRugged Stainless Trim:\u003c\/b\u003e Heavy-duty stainless steel mid-pipe, internal core, and Euro-style end cap provide superior trail impact durability.\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eModular Tuning:\u003c\/b\u003e Accepts optional FMF quiet turn-down inserts and screen-type spark arrestors for track-to-trail sound versatility.\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eUniversal Header Fitment:\u003c\/b\u003e Integrates seamlessly with your stock OEM head pipe or upgrades directly to FMF Powerbomb and Megabomb headers.\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eChampionship Pedigree:\u003c\/b\u003e The same high-performance exhaust design trusted by premier factory racing teams and elite off-road competitors.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cb\u003eMoto-House MX Pro Tip:\u003c\/b\u003e\u003c\/p\u003e\n\u003cp\u003eThe Yamaha Raptor 700 is an absolute beast, but its potential is heavily choked down by the quiet, heavy stock muffler box. Bolting on this Factory 4.1 slip-on is the single fastest way to wake up that 686cc power plant, giving it a crisp throttle response and a throaty, deep rumble that sounds incredible. \u003cb\u003eInstallation Tip:\u003c\/b\u003e When sliding the new mid-pipe onto your header, apply a thin, even layer of high-temperature copper silicone sealant around the junction slice. This ensures a 100% airtight seal, preventing annoying popping on deceleration or minor air leaks that can throw off your engine tuning. \u003cb\u003eTuning Advice:\u003c\/b\u003e Because this free-flowing exhaust significantly increases airflow efficiency, we highly recommend pairing it with a high-quality aftermarket fuel controller (EFI tuner) to adjust your air\/fuel mapping. This prevents a lean running condition, ensuring maximum safe horsepower gains and cooler engine operating temperatures.\u003c\/p\u003e\n\u003ctable style=\"width: 100%; border-collapse: collapse;\"\u003e\n\u003cthead\u003e\n\u003ctr style=\"background-color: #f2f2f2;\"\u003e\n\u003cth style=\"border: 1px solid #dddddd; padding: 8px;\"\u003eMuffler Material\u003c\/th\u003e\n\u003cth style=\"border: 1px solid #dddddd; padding: 8px;\"\u003ePipe \u0026amp; End Cap Specs\u003c\/th\u003e\n\u003cth style=\"border: 1px solid #dddddd; padding: 8px;\"\u003ePrimary Compatibility\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd style=\"border: 1px solid #dddddd; padding: 8px; text-align: center;\"\u003eRaw Premium Titanium Canister\u003c\/td\u003e\n\u003ctd style=\"border: 1px solid #dddddd; padding: 8px; text-align: center;\"\u003eStainless Steel \/ Euro End Cap Style\u003c\/td\u003e\n\u003ctd style=\"border: 1px solid #dddddd; padding: 8px; text-align: center;\"\u003eYamaha Raptor 700 (2006 - 2012)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"border: 1px solid #dddddd; padding: 8px; text-align: center;\"\u003eWeight: 5.4 lbs (Lightweight)\u003c\/td\u003e\n\u003ctd style=\"border: 1px solid #dddddd; padding: 8px; text-align: center;\"\u003eAccepts Quiet Inserts \/ Spark Arrestors\u003c\/td\u003e\n\u003ctd style=\"border: 1px solid #dddddd; padding: 8px; text-align: center;\"\u003eYamaha Raptor 700R (2013 - 2023+)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"border: 1px solid #dddddd; padding: 8px; text-align: center;\"\u003eExhaust Configuration: Slip-On\u003c\/td\u003e\n\u003ctd style=\"border: 1px solid #dddddd; padding: 8px; text-align: center;\"\u003eFits Stock, Powerbomb \u0026amp; Megabomb Headers\u003c\/td\u003e\n\u003ctd style=\"border: 1px solid #dddddd; padding: 8px; text-align: center;\"\u003eRiding Style: Sport ATV \/ Off-Road\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003ch3\u003eFAQ Questions\u003c\/h3\u003e\n\u003cp\u003eQ) \u003cb\u003eDoes this muffler come out of the box with a USFS-approved spark arrestor pre-installed?\u003c\/b\u003e\u003cbr\u003eA) No, the Factory 4.1 model is shipped as an open race-course muffler optimized for maximum unrestricted airflow.
