Security Question


Repack Kits

Due to the construction of our mufflers, we do not offer repack kits and we don’t recommend trying to repack an HMF muffler on your own. There are specialized tools and parts required to repack our mufflers correctly, like a pneumatic rivet gun. HMF highly recommends filling out the form and sending in your exhaust for repacking service, unless you have prior experience repacking exhausts. If you still have the tools and skills to tackle a job like this, we offer full instructions of the repacking process.

Return and Exchange Terms and Conditions

Shipping damage must be reported to HMF within 1 week of receipt. Shipping damage is not the responsibility of HMF. HMF will assist you in filing a claim with the shipper so you may be reimbursed for the damage.

Any item being returned to HMF for refund or exchange must be in new, resalable condition with all parts include in the original packaging. Exhausts that have been fitted or run will not be exchanged or returned. All returned items are subject to a 20% restock fee. Refunds will not be granted for items that are returned without a copy of the original order or packing list.
