Here in another option to eliminate the whistling on the race pipe. I cut a piece of aluminum to fit in the pipe and pushed it up to the bar, then glued it in place using JB Weld. Whistle is gone and the good Ducati sound now plays from the pipe.
Very interesting... So like a center fin from the bar to the lip of the exhaust?
Thanks to the topic starter for this great tip. I also didn't like the whistling sound, but without the db killer the sound is just a little too much, and this is the perfect fix!
I also like the look of the exhaust better with the db killer in place.
I just took out the db killer and used a small loose hechsaw blade to cut the bar out. You can't even see it has ever bin there. Now the Scrambler sounds perfect!
