Hi all,

I just installed the OBX header + OEM CAT onto my 04 MINI ONE CVT, everything goes well (I hope) and love the performance .There is two problem bugging me :impatient , hope someone can help me out

1. When ever I reach 2000-2500 RPM, there is some vibration underneath the car (/seat, my butt can feel it). If I rev over it than the vibration is gone and when the rpm drop back to above range, it vibrate again

2. It also making sound when ever I mild/hard accelerating... it sound like "wooooo" (like a tunnel sound)

Any idea? Pls hlp

Thanks a million
