Welcome to our re-work program to upgrade your Gen2 Raptor HX Series muffler with our Helmholtz resonator. We offer two options.

Option 1 (RETURN)

Return your HX series muffler for us to upgrade it.  This option will be required you to ship us your HX series muffler. Once we receive it, we will need one business day to upgrade your muffler.  Your upgraded muffler will be returned to you via UPS or FedEx Ground.

Option 2 (SWAP)

We will ship you an upgraded Helmholtz HX series muffler for you to swap with your HX Series muffler.  You will be charged a $500 refundable core charge for this option. We will process the refund when we received your HX series muffler.  A UPS or FedEx shipping label will be sent with the upgraded HX series muffler to be used for returning your original HX series muffler. This option can take up to 4 weeks depending on availability.
