HKS Hi-Power exhaust
187.8 HP 182.1 TQ
Pros
As with most HKS products, fit, finish, packaging and presentation are second-to-none. As an added bonus, we gained a whopping 19.7 hp and 14.2 lb-ft of torque. This exhaust really unleashes the beast in this engine. The majority of the power came on from 3500 rpm through red line. The exhaust note is surprisingly tolerable for the 85mm piping. The stainless muffler canister is first-rate.
Parts
Muffler, B-pipe, gaskets, bolts, sticker and instructions
Cons
All the instructions are in Japanese but at least the pictures are easy to interpret. Although it has a sweet exhaust note some may find it a little loud, and there is no silencer included.
Installation Time
45 minutes
Temperature
Air temperature at 71.5 degrees FahrenheitTemperature difference from previous
run: -2.5 degrees Fahrenheit
Tools
14- and 17mm combination wrenches, 14- and 17mm sockets, ratchet and WD-40
Notes
The installation was straightforward. The disassembly and reassembly went off without a hitch.
Tune It.
Power is everything
