Thunder Mfg Dyno Graphs
Attention: Due to counterfeit air kits being produced and an overwhelming number of tech calls for these products we have removed our instructions from the web. All of Thunder Mfg. products include instructions in the packaging. If you have a Thunder Mfg. product and need a replacement set of instructions please feel free to email or call us with proof of purchase and we will be more than happy to assist you. Sorry for the inconvience.
All Dynos were done at the Thunder Mfg. Dyno tuning facility. The only modification made to any bike was the addition of our air kit. Some bikes already had aftermarket exhausts while others were completely stock for the baserun. We are trying to show just the gains made with our air kits only, not the combimed gains of many products.
