Review
Fitted this on my ride, and definitely am satisfied with what this exhaust has to offer. While idling, it gives a soft, mid-note bass, quietly waiting. While on the move, it is quite loud, having a lower bass. Perfect for those looking for an exhaust that has perfect acoustics for nice-sounding exhaust enthusiasts. Soft enough to not attract the cops, loud enough to give you awesome rides. Performance wise, there are noticeable upgrades in pickup and engine response. In short, this HKS HKS Hi-Power Ti is for those who still want a quiet muffler but want others to know it's not stock. The Hi-Power fits the bill perfectly. Fitment is good and it's rattle free.

What I like
The sound this exhaust produces adds the feel of sports driving with my Civic. The slight performance boost is also quite a treat for me!

What I do not like
The heavy price tag for this particular exhaust will turn off most acoustic enthusiast if they had never heard how this system sounds.

Review
My only interest out of the exhaust was the sound. I have watched numerous YouTube videos, and I liked how it gives the low bass sound. I assumed it'd be much more awesome-sounding on my Mitsubishi Evo 9. Then, I took my car to a muffler shop. I asked the mechanic to take off both the resonator and the muffler so it is straight from the catalyst. There was a plenty of space to insert where the resonator used to be. The large 120mm tip nicely fitted on the cutout on the rear bumper. The sound was more than I expected. What can I say... I just love it. This gave me a strong internal resonance. It feels like I have a surround speaker all around my car. The internal resonance becomes the strongest at 2,000rpm. This is exactly where the engine stays at when I maintain the speed on the road. Even at 60 or 70 mph, it's still a deep sound rather than a high-pitch sound. Overall, I totally recommend this item. It's worth paying the money!

What I like
The sound that it gives really hypes me up!

What I do not like
Expensive piece of muffler.
