When I removed the 3.5" Aerochamber, it went from 12 up to 18 psi boost because the dP across the turbine increased, allowing it to spin the compressor faster.

I have the loudmouth behind some turbos....sounds good. Not as raspy as it was N/A. It does give a loud pop though between shifts when changing gears at 5,000+. And you can hear the turbo, or turbos, through the exhaust quite well.

I'd beg to differ.....when I open my cutouts, I get about a pound of boost more. There is some restriction. That and it's a TON quieter through the exhaust. Turns it from a roar to a more "airy" sound of rushing water.

I run a single 3" in 3" out Dynomax muffler on my setup, its very quiet around town, and I have a cut out for the track. I bought the Dynomax intermediate pipes separately through summit and the muffler also from summit, I then made my own tail pipe and tip. My cutout is Borla style right before the muffler.

The Muffler was the highest flowing 3" inlet/outlet I could find. I prefer the sound of the "turbo" muffler as opposed to a "race" muffler.
