Default No Muffler.. Bad?

Pulling the factory off...
Putting FE kit on...
And attaching just a small side pipe to dump exhaust (no muffler)..

What are the effects of this.. I've searched and searched with no real answers.. Help me out here guys...

Thanks
DH

not sure how it will affect the bike, but on my last truck i ran no muffler instead of putting aftermarket on and it lost low end power....

and it will be ridiculously loud!

depending on how far away from the head your "dump" is, it's a possibility that you might burn some valves. but as long as you keep it reasonable (i.e. after the header) you should be fine. And everyone above is correct.... your neighbors will hate you because it will be rediculously loud. Oh yeah, watch out for that "popping" with all that unburnt fuel.

He's correct you will burn your valves up and loose horsepower. The engine needs a certain amount of backpressure to work and preform properly. So I would suggest dealing the factory pipe until you can afford a slip on exhaust.

+1. EXACTLY! (and +1 to the neighbors hating you too.)

Not to mention, you just voided your warranty entirely.

you void the warranty as soon as you put an aftermarket exhaust or pc3 on the bike, or disable the PAIR.
