Exhaust plays a big roll. My car with DUMPS(and open dp's)...I never heard a turbo or BOV...now...with tail pipes(note-I did add billet compressor wheels) I can now actually hear the turbos lighting off. So,..it's either the car is quieter now inside the car...orthe billet wheels make that much of a difference. I will know for sure once we get the car on the dyno to compare to older videos possibly.

Billet s480 T4 .96 on my junk with the gate plumbed into the exhaust, 4 inch exhaust to a hooker muffler, absolutely screams under boost. I've had passengers plug their right ear when the windows are down. Topped the set up with a procharger big red race valve.
