HKS HI-POWER exhaust installed and review

Baddriver · 05-01-2010, 09:05 AM

I had mine installed along with an amuse catdelete. I'm happy with the sound but not as impressed as the videos/sound clips from stillen and 5zigen.

Unfortunately, I also installed hks intakes and I LOST POWER. From 268 whp to 257, dynojet. We let the engine cool and put ice on the intake tubes and engine and it produced 275. The Shop engineer thinks it's the intakes and suggests that I put back the stock box. Admittedly, it's about 4 degrees warmer, but that shouldn't result in dismal numbers.

Well try to do some custom intake box/enclosure and see if it gives cooler air. If not, it's back to the stock intakes. I hope hks kansai produces a similar intake box seen in evos.
