If this is directed at me, the bike was like that when I got it. Couldn't tell you, but it seems to run fine, and it hauls ***............

 

I rarely rev it past 6. That's moving at a pretty good clip and it is ridiculous at 12K rpms. It really is ear splitting.

 

have had mine chopped since the beginning of 08, havent had any issues. its loud as **** but thats it. i have only had to change my oil.......thats the extent of what i have had to do to the bike.

 

yeah it will reduce back pressure, depending on how it's done some more than others but will it hurt anything, no. hotbodies made an undertail exhaust for the early 2000's gsxr1000 and all it was is just a bunch of bends no muffler at all, it was loud kinda didn't care for the tone but it was different at the time and loud.

here's mine on the dyno, was recorded off a helmet cam so quality kinda sucks but you get the idea

think im going with the Voodoo... i got a guy who could custom fit it onto my bike so it sits exactly where i want it. Plus it sounds great.
