If you're getting bad port noise, you need more port area. It would be better to get one pipe that's larger, like say 6" if you can get enough port length and still maintain desired tuning. Don't do two 2" ports on each side. BAD IDEA.You want more area in the middle of the circle that is the port. Air moving in and out past the rough edges will cause a "chuffing" sound once it starts moving fast enough.Like Jeff said, flares would be a good place to start. Might be able to keep a single 4" port</blockquote>
