I have a '99 vintage CR and those pipes were restrictive. About three years
ago I got the unrestricted pipes from Don. Big difference. I used a small mirror and a bright flashlight and could easily see the baffle with an 1 1/2"
hole. The new pipes are the same diameter as the outlet and had an open
mesh wall instead of solid pipe inside - plenty of room to breathe. They
were louder than the others but if you were easy on the pedal no problem
with too much noise in town - just sounds mean.
