Real world dyno testing is what Dyno Cell is all about. We constantly hear stories about a product making "X" amount of horsepower but when tested the power produced is most times much lower than stated. Dyno Cell is way to keep manufacturers in check and keep them from posting absurd horsepower increases from their products. When we heard that Stillen was claiming 16 horsepower at the flywheel from their 350Z exhaust system we had to find out for ourselves. We have performed several exhaust tests on the 350Z in the past and the biggest gain we have seen was about seven to eight horsepower. Claiming 16 horsepower would double what we have witnessed. So we found a bone stock 350Z with 20,000 miles on the odometer and took it over to Stillen.
The HKS Hi-Power 350z Exhaust system features adjustable length dual titanium tips, with full 304 stainless steel piping for long life. A stock Nissan 350Z saw an additional 14hp and 7lb/ft of torque when equipt with the HKS Hi-power. .
