"loose/muddy" sound after 1200 miles

i recently completed a ride on my 09 900 custom SE and noticed that towards the end of my ride my the exhaust sound was different. i now have 1250 miles on my bike, having had 600 when i began. i replaced the exhaust at 300 miles with cobra dragsters; marbled it until around 600 miles; had my first servicing done at the local kawasaki dealer; installed a FI2000r directly after and, after toying around a couple times, settled the pots to 3-2-1. i had suspicions that i had simply broken the engine in but do not like the "loose/muddy" sound that i now have. i prefer the crisp growl i had prior to my trip. i also feel as if the throttle is less responsive, meaning: my acceleration feels more loose than it did previously. i noticed yesterday that for the first 20 minutes i rode yesterday it felt like it had before but, after hitting the highway, the sound and feel returned to the new, undesirable way. does anybody have insight on the cause, or better yet, the cure to this?

in addition: the trip included a lot of interstate riding at 70 mph, some city driving, and heavy rain.

The only thing that comes to mind is either the FI2000R settings or maybe you some how moved the idle vlave?

I'd try unplugging the FI 2000 and see if that's the problem.

I noticed a change in the exhaust sound after about 3000 miles it seemed to have occurred after I did a complete debaffle on the stock exhaust

Sorry I know that was ZERO help but I just could not resist.

Start by going backward on things you've touched and disconnect the Fi2000, you don't need it anyway just for a pipe change.
