Slimsfab ironhead two to one performance pipe

Here is a set of two to one pipes i built for ironhead application , they are great performers through the whole rpm range,When you go to this style design the performance curve is alot smoother across the board and is a touch more quiet!If you are looking for shitty loud and dont care about performance these are NOT for you ,SLIM..... to some of us disturbing the piece is just as important as a quick bike, I like both!, thats why I ride TWO STROKES!
