Is that stock exhaust too? A bit hard for me to tell. Also, whats that strange fluttering noise the SC makes around 0:55 to 1:05? Just a harmonics thing with the mic or something else...?

oh yeah that's nothing for engine movement. fwd cars move like crazy compared to that. looks like it's coming together, gonna be interesting to see these kits come to fruition. my question is wtf is the sound at 58 seconds sounds like a fluid pump screaming or belt slip.

Yes we are still testing With stock exhaust and cats, we will be running more boost on the stock exhaust then we will switch the exhaust out and retest again. as for the noise it is the bypass valve flutter.

Anyway to eliminate that flutter? Not much of a fan. I had the same noise on my SC mustang whenever i let off the throttle. Or is the flutter intrinsic to centri SC's with a recirc set up

Withe the air filter in place and the bypass valve hook up in recirc set up, you wont here the flutter noise.
