HKS Hi Power Spec L Dyno Result
We recently Dyno tested the HKS Hi Power Spec L Exhaust system.
Dyno was a Dynojet 424LCX with Twin Eddy. The engine oil was the same 0W/20 that was used in our original Dyno. The test was done with the same K&N drop in filter. Testing was done in 5th gear. I first Dynoed the car with the HKS exhaust sytem on and was suprised to see 2hp less than our first dyno a couple months ago. So I changed back to the original exhaust system asap and put it back on the Dyno. Our car is now lower 5hp from when we first dyno tested it back when the weather was cooler by 20 degrees F. So the gain with the HKS Hi power spec L back to back with the stock exhaust with the most constant reading was. +3.12 hp +2.91 tq   Will post a video when it's done. Great looking exhaust, and sounds very smooth. Not too loud but just enough to enjoy!  Ishii |

I love how high quality the parts are, but man I hate the big cannons for the exhaust. I guess that's what makes this hobby so much fun, is the difference in styles

I recently installed mine as well and I defently agree with you. The sound is not loud at all and gives you the option of a crosspipe and headers without been crazy loud. The quality is hard to match as well.
