Hey guys. I have a 2013 jk 2dr sport automatic. I have put an afe stage 2 cold air intake, glasspack exhaust, 16 in rims with 285/75/16 cooper stt tires and a teraflex 2.5 budget boost. When I'm driving and I floor it there is a loud squealing noise. It doesn't matter if I floor it from a dead stop or if I'm already doing 65 on the highway and floor it. I'm pretty concerned. It seems like when I put it in shift mode on the highway and I'm doing 65 in 5th gear and I floor it it drops to either 2nd or 3rd on its own and then I hear the noise. Just curious if anybody has any idea what this could be?

 

my guess would be a pulley that's seizing up and your belt is slipping over it with the sudden change in rpm. chances are you'd hear it at start-up too so I'm guessing. pull off the belt and check them out

 

Did you hear the noise prior to your add ons?

 

To be honest I never floored it before the add Ons. It sounds so good now with the cai and the glasspack. That's how I found out about the noise.

 

Is it more of a whistle? Because the intake will make it whistle really loud

 

you are probably just hearing your intake sucking in a butt load of air

 

That's what I'm saying mine whistles like a turbo. Prob what he may be hearing

 

No it's not the cai. It sounds more like a burnout but I know that's not the case. Lol it last about 3-4 seconds and then stops.

 

So you know the sound the Cai makes when it whistles?

 

Well I've had cai on other vehicles and this is the first time I've had this problem.
