jetZILLA ProTuner Tuning Sleeve

Post by larry cottrill » Thu Apr 08, 2010 8:00 pm

Yet another new offering, for serious experimenters only. Use this anywhere a permanent tailpipe tuning device is needed or desirable. For example, you might want to tune for optimum length because of altitude variations, experimenting with widely differing fuels, etc. Designed by Larry Cottrill, expertly fabricated in heavy gauge stainless by Jim Russell Design of Des Moines, Iowa USA:
