You gotta love Rick. He could have added his beloved Power Pipe much later in the test to really make it look good, but he was confident it would help at this power level, and it did. While it wasn't like a shot of nitrous, the Power Pipe ($232.66) improved the numbers across the board, and stacked 2.5 hp and 1.3 lb-ft onto the peaks. If you aren't familiar with AFM Power Pipes, these are mandrel-bent inlet tubes designed to smooth and enlarge the inlet path. They are popular additions to superchargers, often yielding more boost, but Rick also has a selection of naturally aspirated parts as well.
