Question About Custom Exhaust

I like the look of these exhaust, but I am just concerned about bypassing the O2 sensor and such. What are the consequense of putting these exhaust on?

I asked the sell the same questiong as my original post and this was his reply..

I have a custom exhaust on my M109R already and there are no electrical connections anywhere. There is a mechanical kind of a butterfly set up with cables for something on the stock system but I am not really sure what it is for...would guess for some sort of smog device. My exhaust came with a little half moon shape piece of metal that I screwed onto the bike by the engine where the cables used to run on the stock exhaust but I am not sure what it accomplishes. Sorry I can not be of more help but I hope this answers some of your question. Regards, Mark

Any assistance about what I need to or purchase to make everything right would be appriciated.

If you live in the U.S., you don't have to worry about the O2 sensors since we don't have them. If you live in Europe, Asia or Australia you have them and need to get O2 sensor eliminators, though some say you can just unhook them with no problems. Check out the Australian board since they deal with it all the time.

The butterfly device the seller mentioned is what you see as the SET valve on here. It's an exhaust tuning device, not a smog device. It has an actuator that the computer controls to position the butterfly. You can't just unhook it or you get an FI light, which is what the half-moon piece he mentioned is for. It mounts on the actuator and fools it into thinking it's still hooked to the exhaust. You either need that piece or you can pull a wire on the computer to disable it. Either is easy to do. There are links in the FAQ at the top of this page on how to do either.

Other than that, the only consequence I see of installing them is a rapid loss of hearing. Those suckers have to be loud. :eek:

And you'll probably need a fuel tuner if you don't already have one.

There's a good reason behind the nickname for those pipes... "Streetsweeper!" :evil: Speaking from experience... just warn your friends not to ride on your right side. :D For that matter, watch out when you start your bike up while parked on the right side of the street next to a curb... you're going to get blasted with debris. :-\
