Had to replace my Thunderheader when it just plain turned to dust. (It was very old) The only choice was another Thunderheader. I run a EV-27 and E carb with this pipe and everyone thinks I have installed a big bore kit. This header really works.

The exhaust is an awesome product, I have used it for many years and have also suggested it to numerous people and customers of mine. The latest experience with Rich Products (ie Thunderheader) has been less than desirable. After 74 days from order, the exhaust has arrived. All components are in excellent shape and all pieces needed are there. The only downfall is for my customer to have to wait as long as they did, the engine build has been completed for 12+ weeks. So bottom line is, be prepared to wait.

Important Product Notes

Note: Please see U.S. EPA and your respective state and local regulations to confirm noise and emission compliance.

Important Exhaust Notes:

• Note: With any new exhaust, we recommend changes to carburetor jetting or use of an aftermarket fuel injection control module.

• There is no warranty on exhaust pipes and mufflers with regard to any discoloration. Blueing is caused by tuning characteristics, cam timing, carburetor jetting, overheating, etc. and is not caused by defective manufacturing. No refunds on exhaust pipes once motorcycle is started unless there’s a manufacturer’s defect.

• Flanges and retaining rings are not included with most aftermarket exhaust for 1984-2013 Evolution and Twin Cam models. Re-use your existing hardware, or purchase replacement hardware.

Shipping Note

Additional oversized shipping charges will be applied for expedited shipments within the contiguous U.S. Shipping charges outside the contiguous U.S. are calculated by weight and dimension during checkout. Due to state regulations we cannot ship this item to the state of California for some motorcycles.
