Does anyone know if there is a special tool needed for the adjustment nut on the JCW exhaust tips? I want to adjust them slightly but a 7MM hex does not seem to sufficient.

 

I think you need a wrench that makes lots of sparks to get that off.



Make sure that pipes are cool. After last Saturday they may still have some heat in them.

 

I think it's a 4mm.

 

Actually it is 3mm. Thanks for getting me to think differently. When I looked at the bottom of the exhaust tip all I saw was the larger hexagon nut. It did not occur to me there was a smaller hex screw in there. Thanks!
