Yamaha XT 660R (2004) Slip-On SP Series Exhaust System
Yamaha XT 660R (2004) Slip-On SP Series Exhaust System for the Yamaha XT 660R (2004) We have developed an Akrapovic SLIP-ON SP series partial exhaust system for the popular Yamaha all-rounder. The Akrapovic SLIP-ON SP series system is intended for everyday riders looking for a great combination of price, quality and performance. The Akrapovic SLIP-ON system with the use of 94dB noise damper insert conforms to FIM Enduro regulations on exhaust system noise levels. PERFORMANCE max. rear wheel power HP / rpm Power: the utility and purpose of the Akrapovic SLIP-ON SP series is shown in the power curve, which is identical in shape to the stock curve. The system delivers an increase in power throughout the entire rpm range, following the same pattern as the stock set-up. The increase is nearly the same throughout the range, with a slightly higher increase near the top and in the overrev range. At 6000 rpm the system delivers over 44 HP. Torque: the torque is also increased throughout the range, and also follows the stock curve. The maximum difference appears in the middle of the range, which is right where you need it for everyday riding. AKRAPOVIC max. increased power 42.8 / 5950 44.1 / 6000 2.1 / 6500 (measured on SuperFlow Cyle Dyn) CONFIGURATION PERFORMANCE Measurements of the Akrapovic SLIP-ON SP SERIES system on the YAMAHA XT 660R (without noise damper): stock CONFIGURATION header tubes collector link pipe material - - STAINLESS STEEL tube shape - - CONICAL interference crossover tubes - lambda sensor - header tube inner sleeves - header tube flanges - header tubes - collector connection - collector / header tube link pipe connection FREE-FLOATING + METAL CLAMP + SILICON SHIELDED SPRING link pipe - muffler connection FREE-FLOATING + SILICON SHIELDED SPRING muffler inlet cap /outlet cap STAINLESS STEEL / STAINLESS STEEL muffler metal interior STAINLESS STEEL muffler outer sleeve TITANIUM muffler clamp CARBON-FIBER OFFROAD muffler bracket - noise damper FIM ENDURO 94 dB heat shield - CONFIGURATION Off-Road Road Program The configuration of the system for the Yamaha XT is 2-2, which means that the twin header tubes are led into two mufflers. The muffler outer sleeves are made of titanium, while the interior and the inlet and outlet caps are of stainless steel. The link pipes are also stainless steel, and conical for improved exhaust-gas flow characteristics. The link pipes and mufflers are attached using free-floating joints held together with silicon-shielded tensioning springs. The mufflers are led to saddle height on both sides of the bike and are attached to the frame using Akrapovic carbon-fiber clamps. The link pipes are also attached to the header assembly using free-floating joints, this time held together with metal clamps. The Akrapovic SLIP-ON SP series contains a FIM Enduro 94dB noise damper, and thereby conforms to FIM regulations for exhaust system noise levels for Enduro competition.
