As discussed previously, the standard Honda pipes make very good power across the rev range.

They are heavy, and maybe don't look as trick as aftermarket, but they do at least produce excellent power.

Cheapest option is to replace the end cans only, giving you a trick look and slight weight saving, whilst keeping the stock chambers for their power and free-ness!
