So i think i have got thi down...
If you wait for the valve in thre exhaust to open up,turn the ignition off,unplug the plugs going into sensor and remove or cut brown wire #30..This is like diong the TRE mod except your gear counter still works?
hmm, sounds pretty simple. so what exactly is the purpose of the set valve. from what i understand (please correct me if i'm wrong) the purpose is to control the sound waves coming from the exhaust side of the engine. it changes the shape of the exhaust to make the bouncing sound waves return at the correct time (kinda like why a two stroke exhaust has a specific shape). so if im correct on that assumption, what are the possible consequences of taking away this valve?

If you don't eat your meat, you can't have any pudding.
It's basically a sound reducing device. The US EPA and several other nations' regulator bodies require a 'pass through' noise test, as well as stationary noise requirements. Suzuki, and others, have found a way to pass these tests without significantly hurting performance by closing this exhaust chamber valve at strategic moments commensurate with test requirements.
To pass these tests without this type of valve would require a far more restrictive and power robbing exhaust system.
The sell this device to the consumer as a 'power enhancing feature' to discourage it's removal, or at least to discourage it's disdain.
In fact, it has been shown on the dyno that this type of obstruction in the exhaust collector does not enhance power, but does in fact diminish it to some degree.
If it was a true power enhancer, every racing motorcycle and every aftermarket pipe bender would have them installed on their equipment.
I did this mod tonight after I got out of work and it took me about 15 min. I didnt really notice a difference in the sound but then again it was still in my garage..its was raining outside. One question, when I take my bike in to get serviced, should I reconnect everything to stock so they wont mess with me about the warranty? By the way, awesome directions a nd pix!!
