Injen Titanium Tip vs. HKS
A perfect example of how "sounds great" or "sounds bad" is TOTALLY user dependant. We used to have the Injen on one of our Z's (Kwame's). It doesn't just drone at low rpm's, it droned everywhere. Yes, it gave good gains, and yes, fit and finish was good, but it was LOUD, plain and simple. If that's what you are after, or can put up with, then that's fine. All depends on your personal threshold and personal preference.

Maybe next time I'll make a post with some in depth audio analysis of each exhaust, including the frequency, amplitude and tone of the exhaust sound at every possible rpm. Should be one hell of a spreadsheet.
