Default undertail exhaust suggestions for '04 F4i

Hi All,

I have a 100% stock (minus a slip-on) '04 F4i and i am thinking about getting an undertail exhaust for it. Can those of you with f4i's who have done similar projects post pictures and websites of the outcomes?

Thanks!

Here's a pic of my bike so that you know what i am starting with...

they do look coo, but i believe you lose HP doin that.. the torque numbers might be better bcuz of back pressure. Im suscribed to this thread either way bcuz im always interested in new exhausts. I have for sale a GP style slip on for a f4i that sounds amazing. I run a Leo Vince cut down slip on and it sounds good even with the dent on the back, that might be what makes it sound mean LOL

I'm not 100% but I believe you have to replace your subframe in order for it to work.

haven't seen one done with a 'nanner seat before. some have done it with the split seat, some replace the rear subframe with a 600rr, and some even replace the swingarm (so you don't have to route the exhaust outside the frame.)
_Z_ would probably be more than happy to offer his insight in the project.
