in my experience, titanium always sounds good. Ive had titanium exhausts on my S2000, RSX, Evo X (which I thought would sound like garbage because the engine sounded like a vacuum but it didn't) and finally S14 with a KA24. None of them sounded bad. Worth rolling the dice, I would get it but Ive already bought 2 exhausts (COBB mistake, then Thermal) It's too bad it wasn't around in 2014.
Edit: it MAY be loud though.. as all of the above were loud.
