Hey, i have a problem with my injen exhaust, after driving with the exhaust from 400 to 3k miles the exhaust started whistling on me each time i press on the gas, some times it goes away but comes back, it doesnt sound as it did when i bought it that deep tone, it just whistles all the time, any one had this problem befor or is this is normal? thanks.

 

Check the seals and make sure that there is nothing in the filter. It also may not be your intake, it could be something else.

 

check your donut gasket, its between the midpipe and the injen exhaust

 

Have an intake?? All intakes and even the stock air box whistles a partial-to-mid throttle. If you had an exhaust leak, you would hear it when idling. Noticable "pfffpfffpfffpfffpfffpfffpfffpfffpfffpfff"

 

nope i dont have anything other then the exhaust and no intake.
