My Ride: My Bimmer's info is in my sig, so I'll tell you about my garage toy. It's a 1997 Porsche Boxster. The car is black on black and I have replaced every single thing on the car (interior, exterior, drivetrain, suspension) except for the sheet metal and the convertible top (both of which will be next I guess). I love my Pcar more than any other car I have ever owned and will probably keep it for the rest of my life.
Porsche. There is no substitute.
How do I keep the butterfly valve on my 2nd exhaust pipe open all the time so I get a little more sound at idle and lower speeds? I have a 07 550i
And does anyone know... at what speed or RPM does it open up?
