 2005 Nissan Frontier Nismo Exhaust Compare
9. Here you can see the differences between the OE exhaust system and the JBA setup. Aside from the increase in pipe diameter, the JBA system contains a freer flowing muffler and a less restrictive Y-pipe.
 2005 Nissan Frontier Nismo Catalytic Converter
10. The only portion of the factory system we reused is the OE catalytic converters. Here, the JBA technician installs the driver-side cat to the new JBA header.
 2005 Nissan Frontier Nismo Round Muffler
11. We're not sure why JBA uses a round muffler in the kit instead of an oval type shown in its marketing brochure. Our guess is that someone used the wrong muffler for the brochure's photo shoot. After the fact, we questioned JBA about this, and they assured us that the round-type muffler included with our kit was indeed the proper unit for our truck.
 2005 Nissan Frontier Nismo Tailpipe
12. This shot shows the tailpipe section of the JBA exhaust system. Notice how it tucks nicely up and over the axle, while maintaining critical clearance between the spare tire and the hot pipe. The polished stainless steel tip adds a nice cosmetic effect, rounding out the whole package.
 2005 Nissan Frontier Nismo Tack Weld
13. We had JBA's technician add some tack welds in key areas to prevent unwanted movement. This step, while not necessary, will help prevent leaks in the long run.

As you can see from our testing, we gained 15 lb-ft of torque and 12 hp at peak performance. Not bad for a simple exhaust system.
