Has anyone noticed on the RT-1 slip-on for the 01-03 f4i, the end cap is restricted. The inner outlet is like 1/2" smaller diameter then the actual outlet. Has anyone ever cut this out? After seeing my brothers Micron pipe, i figured it would only make sense.

 

ahh...mines not like that. u have a pic of this?

 

Oh never mind.. That's just the diameter of the inner core.. I ended up cutting the pipe down 5" so I'm not too worried about it now.. Thanks.
