I purchased a 3" Corsa cat back from JonB in November 2002. A problem developed with the mufflers. I called JonB. He immediately three - wayed in the Corsa rep. After a brief discussion, it was agreed that I would pay for a new rear assembly which would be drop shipped to the installer subject to a refund if an autopsy by Corsa showed a defect. Today I was informed by JonB that Corsa completed its autopsy and that they found a defect. My payment is being credited back to my credit card. This was an exceptional level of service by JonB and by Corsa. The Viper community is very lucky to have such a fine vendor and a distributor of that vendor. In today's brave new internet world it is nice to know that there are still people dedicated to a quality product and quality service. Thank you JonB and Corsa.
