Tori, Both pipes are under the bike. The front two cylinders go into one pipe and exit in front of the rear tire and the rear two cylinders join into the other pipe (the one you can see in the pic) and exits towards the front with a turn down. It has a very unique sound. I just uploaded a pic of how the exhaust looks. It is in my gallery.
Hi. Your bike looks very nice. Can you please fill me in with more details on the seat/rear end modifications... Please. Regards Bjorn
