Just put these on a 2007 Street Glide and discovered I need to install a supplied baffle plate to completely block off the left muffler otherwise it draws in cold air and screws up the O2 sensors. There are no instructions on how to install the plate and I'm hoping someone here has some experience.
I tried it without the plate and the bike ,which always ran great, ran crappy, surging, sputtering and cutting out the dash lights!
Not trying to be a smart a$$, but you should contact Kuryakn, they should be able to provide you with some instructions. \\; BTW, post your finding here so others learn as well.
wait- slip on mufflers are causing your dash lights to flicker?

sorry dude- but ive never heard of 'blocking off' a slip on muffler. they should be direct replacement for the stock mufflers.... that is unless youve changed the head pipes too- and didnt reinstall your 02 sensors.

I can tell you that if you go ahead and buy the true duals, you wont be disappointed.
True-duals adversely affect low-end and midrange performance, not to mention are quite expensive, but if that doesn't disappoint a prospective buyer there would be little to dissuade him from buying them.
