Part 8: Exhaust Upgrades
Our '05 Nissan Frontier Nismo has been a favored member of our project fleet for almost three years now. With a potent 4.0L V-6, a sweet electronic rear locking differential, and seemingly perfect proportions, we haven't found a trail that we didn't feel confident attempting. From daily run-around duties to tackling the deserts of Southern California, the Nismo Frontier is well suited to our lifestyle. However, we noticed recently that JBA came out with a set of headers to complement their after-cat exhaust system. We salivated at the idea of increased power and torque in the already snappy package. The rumble of a deeper exhaust note wouldn't hurt either, so we set up a date with the folks at JBA and counted down the days. Once it was go-time, we headed down to JBA's Dyno shop facility in San Diego. After generating some initial baseline numbers, we parked the truck on a lift and the guys at JBA went to town. The install took a majority of the day, but the results were worth every minute.
