blackstns,
If there is ANY risk for trucking companies to void their warranty by installing any kind of performance muffler from anyone other than the maker of the truck, they aren't going to do it, don't you think?
Of course, if Aero got that independent dyno test, and it proved out the savings in fuel mileage, EVERY car maker would sign on to have Aero's product on their car out of the gate, and that would no longer be an issue.
Guess we know what the answer to THAT is.
IMO/FWIW
