Just recently installed a B&M short shifter, Greddy header, and EvoII on my 2000 Si. When the clutch is engaging and at high RPM's, I'm guessing b/c more vibration is present, there is a noise that sounds like metal is vibrating against metal coming from around my shifter area. Not a bad noise like gears are stripping, but more like a vibration noise. Has anyone ever had this problem, seems like it would be an wasy fix. Thanks guys.

 

Yeah, its your short throw on your new exhaust. Typical for people who run larger piping and a short throw. I just made a ding in the piping on my CRX, but I dont even use a shorty on my EK.

 

I've heard the EKs the cat is in the way.
