If you have a fitment, missing part or other problem, please double-check the following troubleshooting guide first.

1. First, reference your instructions sheet and double-check all drawings and instructions.
2. Make sure muffler clamps are installed correctly (refer to diagram.) On many models, there is a right and wrong way to install. Also, verify part numbers on header and tailpipe.
3. Always make sure to install spigots and manifolds on cylinder head prior to installing headers.
4. Always take time to examine problems in detail.
5. When all else fails, call our technical support line at (800) 634-9166. The technical line is open 9:00am - 5:00pm PST, Monday through Friday.

Please have the following information handy:
Year/make/model of motorcycle, date of puchase, place of purchase, batch dates and part numbers (found on pipe pieces.) Also, feel free to ask online at sales@yoshimura-rd.com or fax your questions/problems to (909) 591-2198.
