reviewmotors.co Introduction: Unleash the Roar: Building Your Own 114+ Triumph Moto2 Exhaust Ready to transform your Triumph into a Moto2-inspired beast? While replicating the exact performance of a race-spec exhaust requires advanced engineering, this guide will help you craft a custom system that significantly enhances sound and aesthetics. This project involves welding and metal fabrication, so proper safety precautions are crucial. Proceed only if you have experience or are working with someone who does. This guide provides a general framework. Specific modifications will depend on your Triumph model and desired outcome.
Step 1: Planning and Design Before touching any tools, meticulous planning is essential.
Gather Information: Research the exhaust layout of your specific Triumph model. Note pipe diameters, mounting points, and any existing exhaust valve mechanisms (if applicable). Consult forums and online communities for insights from other Triumph owners who have undertaken similar projects. Sketch Your Design: Create a detailed sketch of your desired exhaust system. Consider factors like pipe routing, muffler placement, and overall length. Will you retain the catalytic converter? Will you create a full system or slip-on? Select Materials: Choose high-quality stainless steel tubing for durability and corrosion resistance. Mandrel-bent tubing is preferred for smooth exhaust flow. Decide on a muffler that matches your desired sound level and aesthetic. Consider using a pre-made header flange that matches your engine's exhaust ports. Determine Tubing Sizes: Match the tubing diameter to your engine's needs. A slightly larger diameter than stock can improve flow, but going too large can hurt low-end torque. Research common exhaust upgrade sizes for your model. Step 2: Gathering Tools and Materials Now it's time to get everything you'll need.
Welding Equipment: TIG welder is preferred for stainless steel, but MIG can also be used with appropriate shielding gas. Ensure you have the necessary safety gear: welding helmet, gloves, and protective clothing. Cutting Tools: An angle grinder with cutting discs and a tubing cutter are essential for accurately cutting stainless steel. A bandsaw can also be used if available. Measuring Tools: Measuring tape, calipers, and protractors are crucial for precise measurements and accurate bends. Fabrication Tools: A tube bender is necessary for creating smooth, consistent bends in the exhaust tubing. A hammer, dolly, and files will be helpful for shaping and finishing. Materials: Stainless steel tubing (various lengths and diameters), stainless steel muffler, header flange (if needed), welding wire (stainless steel), shielding gas (argon), stainless steel welding rods (if using TIG), clamps, mounting brackets, and heat wrap (optional). Step 3: Disassembly and Preparation Get ready to disassemble your current exhaust.
Remove Stock Exhaust: Carefully remove the existing exhaust system from your Triumph, following the manufacturer's instructions. Be sure to disconnect any sensors or exhaust valve cables. Clean and Inspect: Clean the exhaust ports on the engine to ensure a clean surface for the new header flange (if used). Inspect the exhaust studs or bolts for damage and replace them if necessary. Prepare Tubing: Cut the stainless steel tubing to the desired lengths based on your design. Deburr the edges of the tubes to ensure a smooth weld. Step 4: Fabrication and Welding Time to put the pieces together.
Tack Welding: Carefully tack weld the exhaust tubing together, following your design. Ensure that the tubing aligns correctly and that the welds are strong enough to hold the assembly in place during fitting. Fitment Check: Temporarily mount the tack-welded exhaust system onto your Triumph to check for fitment issues. Make any necessary adjustments before proceeding with the final welds. Pay close attention to clearance around the frame, swingarm, and other components. Final Welding: Once you are satisfied with the fitment, proceed with the final welding. Use proper welding techniques to create strong, leak-free welds. Allow the welds to cool slowly to prevent warping. Muffler Attachment: Weld the muffler to the end of the exhaust system, ensuring that it is securely attached and properly aligned. Bracket Fabrication and Welding: Fabricate mounting brackets to secure the exhaust system to the frame. Weld the brackets to the exhaust system, ensuring that they are strong and properly positioned. Step 5: Finishing and Installation Almost done, just need to make it look and sound good.
Grinding and Polishing: Grind down any rough welds and polish the stainless steel tubing to a smooth finish. Heat Wrap (Optional): Wrap the exhaust tubing with heat wrap to reduce radiant heat and improve performance. Installation: Install the completed exhaust system onto your Triumph, ensuring that all mounting brackets are securely fastened. Reconnect any sensors or exhaust valve cables. Final Check: Start the engine and check for exhaust leaks. If any leaks are detected, tighten the clamps or re-weld the affected area. Conclusion: Hear the Difference Congratulations! You've built your own custom 114+ Triumph Moto2-inspired exhaust system. Take your Triumph for a ride and enjoy the enhanced sound and performance. Remember to always ride responsibly and be mindful of noise regulations in your area. This project requires skill and precision, so take your time and prioritize safety. The result? A unique exhaust that's a testament to your ingenuity and passion for motorcycles.
