The head pipe was almost twice the size of stock. Gave it much more horse power and a great sound. I would recomend this setup to anyone. If your thinking about the full system or just the slip on... spend the extra cash ITS WORTH IT. With yoshi, you cant add the header pipe later on. Meaning if you buy the slipon you cant add the head pipe later on it wont match up."
