hay I got me an 06 bolt ss/ss but the rear brake calipers are shot is it like this for everybody? and did the air box mod and the supercharger louder but not as loud as some (like on youtube) them you can hear from the inside mine u have to roll the windows down thanks .

 

The rear break calibers need to be turned in not pressed ...many people think they press in they don't ...supercharger sound is quiet with Windows up ..very normal.

 

I have an lnf and had to replace a rear caliper just get them new and your good to go on the intake mod idk lol
