The driveline was then reattached and now sits in a near level position.
We stuck with Falken when shopping for tires, and the ZIEX S/TZ04 265/40R22 rubber complement the new rollers perfectly.

Our fresh Ford was now sitting low and sporting some style underneath the fenders, but instead of moving straight to swapping in the dB Exhaust system, we made a bee line to Spectre Performance so they could start mocking up an intake prototype, and give us some hard numbers on performance gain.

The free-flowing dB muffler finally made its appearance, and once installed, will not produce any annoying in-cab interior resonance. It will, however, make our project sound like a truck's truck.

The finishing touch to the dB exhaust system—a 12-inch, polished tip that will let other truck owners know who's really packing heat. Even though we didn’t have a chance to dyno the truck post-exhaust installation, we called dB and they gave us their numbers.
