I recently got the dynojet kit for my Mojave. I havn't had a chance to install it or even ride because of the weather but I'll post my findings as soon as I can. I'm considering the IDS 2 exhaust but am a little confused by what people are calling the race series and the quiet series. I assume the race model makes more power but is it too loud? My brother had a Cobra exhaust on his '94 Mojave and it was way too loud. Not even a cool sound, just ear splittingly noisy.

 

rockrider,
in my paper work for the IDS2 supertrapp states that the race series and quiet series offer the same amont of performance as long as thier is no internal engine mods.
I have the race series on my lakota and it is a nice sound, throatier over stock but not to loud.
my sons 80 with a fmf is quite louder compare to the IDS2.
You will not be disapointed!
About the head pipe, I did talk to a guy who had one, but possibly I misunderstood and just assumed it was a white brothers.
