                                                             WARRANTY 
MRD-RACING has the best warranty in the business. We offer a one-time free crash repair for the first 6 months from date of purchase (minor cosmetic damage excluded ) and we will fix any properly maintained pipe that cracks any weld for a period of 3 years from date of purchase. Note: mufflers require re-packing every 50 hrs of hard use. Running your muffler with blown- out packing or using header wrap will cause it to overheat and weaken resulting in premature failure and voids the warranty. please clean pipes before sending them in for repair , pipes sent in  for free crash repair must include $15.00 for new packing and applicable return shipping $
