i had a mbrp turbo back system put on last week, no cat.

sounds great, thing is this morning the turbo whistle didnt sound right.

normally when at idle you can hear the turbo, but this morning you could only hear the rumble of the exaust, sounded like a gasser.

while driving it would take a few seconds for the turbo whistle to kick in and it didnt seem as loud as before.

well i got where i was goin and when leaving it started acting right again.

anybody ever had this happen?
