I belive there is a silencer ring near the intake you can remove to hear the whine of the turbo more.Heres a dumb ? Does it help the turbo whistle at all.
I like to here my turbo whistle.
IM a dealer and i am not aware of that, it was never told to me or brought to my attention thru any correspondenceI have the 4040 and I get drone when towing. But just cruising around, AWESOME sound. I heard, if you order it from the Aero Manufacture website, you get a 30 day trial. So if you don't like the 4040 you can exchange it for the 4040xl. Can anyone confirm?
Ya I did that, bigger air filter, and 4" straight pipe to 5" stacks. Probably not going to get any louder.I belive there is a silencer ring near the intake you can remove to hear the whine of the turbo more.
