Dyno numbers for HKS Hi-Power Ti???

Sound DB level was below 95 DB (for all states that comply with CA law on that). 98's dyno may be more apples to apples for you though.

Sounds very nice but not annoying in any way due to the sub silencers and looks aswesome. Tips are adjustable in lenght as well so it's nice for guys who are running the diffusers and rear skirts.
