Fast friendly service, great fit

Fast shipping great service.

Great service and very helpful with questions I had . H&s mini max is a awesome programmer to delete the oboma filters on diesel trucks today. The pro-flo pipe sounds great and both together gives awesome performance of truck (08 f250 6.4) will give you up to 300hp and gives more mileage on fuel . I went from 11-13 mpg to 15-22mpg on high way and I get about 12-15 mpg in town . Thanks diesel ops for the awesome products !!!!!

Fits perfectly sounds awesome

tuner went in after some tech help pipe was a buggar but went on after a little modification..

Parts needed some modification to fit correctly. Instructions were not included with the kit. It was difficult to find the information for my truck.

I ordered a programmer from diesel ops and did not know how to do what I wanted but they were able to walk me through it step by step
