DME Racing’s Pro Nitrous Motorcycle Exhaust system is a custom 1 7/8″ to 3″ diameter 4-into-1 big tube step header. This system is specifically designed for large engines, NOS motors, and all-out Grudge bikes (short-necked and D-raked). This system fits flush with the bottom case. Some bikes will require modifications to the radiator, see our fitment notes below. FITMENT Kawasaki ZX-10R / 2004-2005 and 2011 Kawasaki ZX-14R / All Years / (Radiator will need to be cut for fitment) Suzuki GSX-R1000 / All Years Suzuki Hayabusa / G1-G2-G3 To ensure proper fitment, you must provide the rear sets you are using. FITMENT NOTES Some motorcycle applications may require radiator modification or repositioning to achieve proper clearance. The oil cooler must be blocked off for installation. When running both a radiator and an oil cooler, a custom mounting solution will be required to properly secure the components. Fairing modification is required on the exhaust/pipe side of the motorcycle to allow adequate clearance for the system. Designed for optimal fitment with DME Racing Billet Oil Pans, but also compatible with OEM oil pans. FEATURES Material: Stainless Steel Comes with o2 Bung – 18mm x 1.25 thread OPTIONS If ordering with a Baffle, the baffle will be installed before shipment. The baffle can be removed. Adding a Baffle will also change the look of your outlet pipe by making it round to fit the baffle. EGT (Exhaust Gas Temperature) bungs are welded onto the exhaust header pipes. Includes 3/16″ adaptors. FAQ’s What fuel map should I use with a DME Racing exhaust system? There is no one-size-fits-all mapping. Our exhausts are built for ALL-OUT race applications. And with every engine combination being different, we recommend that your engine and exhaust be tuned on a dyno or, preferably, track-tuned for maximum results. What is the torque specification for the DME Sidewinder? We do not have an exact torque spec. for the mounting flange bolts, but we can suggest somewhere between 10-16 lb-ft. Do not over-tighten, or you will bend the flanges. Can I order a Baffle for an Exhaust system I already have? Baffles are not available for ‘already-made’ exhaust systems. Systems are either built with the baffle or without. What is the purpose of a baffle in a motorcycle exhaust? The baffles in a motorcycle exhaust system serve several purposes Noise Reduction: Baffles help to reduce the loudness of the exhaust note by disrupting and redirecting the flow of exhaust gases. They contain chambers and materials that absorb and reflect sound waves, dampening the noise produced by the engine. Back Pressure Regulation: They play a role in controlling back pressure, which is necessary for optimal engine performance. Back pressure helps in maintaining the right balance for the engine to function efficiently across different RPM ranges. Emissions Control: Baffles can assist in controlling emissions by aiding the proper functioning of catalytic converters or other emission control devices. They can help in ensuring that the exhaust gases are adequately mixed and processed to reduce harmful emissions. Tuning and Performance: In some cases, baffles can be modified or replaced to fine-tune the exhaust system for better performance. Riders may choose to alter baffles to achieve a specific sound or to improve the engine’s power delivery. Compliance with Regulations: Many regions have noise regulations for vehicles, including motorcycles. Baffles help manufacturers meet these noise regulations without compromising the engine’s performance. Overall, baffles in a motorcycle exhaust system serve a combination of functional, regulatory, and performance-related purposes, impacting the sound, emissions, and engine performance.
