I'm sorry to report that we are experiencing a stock outage on two popular mufflers: Dual Tip Mufflers by Cobalt for NB 99-05 and NC 06-15 are currently out of stock. We do not expect to be able to ship backorders until August 2015.
Our website has a message explaining our expected ship date. These products are available to backorder (click "backorder yes" on the invoicing page of our site during checkout) during this time. We do not charge for backorders until the product ships from our warehouse, and backorders may be canceled at anytime prior to shipping.
If you would like more information about our policies, please click here.
Again, we apologize for this and will ship mufflers as soon as we receive our stock of the products. If you have specific questions please PM me.
Thanks for your time.
