anyone have expierience with the aeroturbine?? 4040xl or 4040??? which one sounds better I dont want drone I have a 5 month old and take long trips

The xl or with resonator, the versions without are race versions and really do very little for sound

I 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?

Heres a dumb ? Does it help the turbo whistle at all.
I like to here my turbo whistle.

aero wont help turbo whine. i run a 4040 with cat and love it, it sounds awesome. without a cat you would probably want the resonated version and put it in the stock muffler position

I belive there is a silencer ring near the intake you can remove to hear the whine of the turbo more.

Ya I did that, bigger air filter, and 4" straight pipe to 5" stacks. Probably not going to get any louder.
