Well I just got my Hayame cat-back put on last night. My friends dad did the install and he didn't have any problems with fitment or anything, it only took him about an hour or so to do it.

I like the look of it, fits nicely on the car. The sound is very loud, its loudest between 2.5k - 4.5k RPM, once my car hits about 5 grand the sound of the intake becomes louder than the exhaust. I feel a little bit of diffrence up top, it seems like VTEC goes by quicker now. Overall i'm pretty happy with it, from what i've red on ClubRSX its suppose to quiet down a little after you get some miles on it. I'll have some pictures up once its not snowing/sleeting outside.

 

Good deal. How much did you pay?

 

$577 shipped from http://www.rsxmotorsports.com, i'd recommend buying from there, their was a mixup with my shipping but he responded to my emails quickly and took care of everything quickly.
