You ‘Walk the Walk’ Not Just ‘Talk the Talk.’ You ROCK!!


Bob of Page, Arizona, installed a Monster Exhaust system, Power Elbow, Big Hoss Diesel Tuner and a High-Ram air-inlet casting on an ’01 5.9L Cummins 24-valve turbo-diesel

I was driving a ‘66 Dodge pickup for 15 years. I finally got an 01' Dodge Turbo Cummins 2500 4-By...Used, but perfect!…white…beautiful! Stock, this truck was awesome. I say was, because with the Banks stuff I put's now a freakin' "Beast." I Love My truck!!! You guys at Banks no doubt "Walk the Walk"...not just "Talk the Talk." You ROCK!!


“Considering the fact that the fuel economy savings are substantial and the fact that the stainless steel exhaust will last the life of the vehicle, the Banks system is well worth the investment.”
