I'm also running the Gen3 intakes with the 12" res FI CBE. Love the sound on downshifts!
I was wondering what the sound difference would be if I took my car back to Tony's shop and added the Long Tube Headers? Has anyone heard the sound difference in person?
I also need to keep the sound at or below 93.0 dBA @ 50ft, the noise restrictions for my local autocross events.
-EDIT- Oh, and I'm on Swift springs and the ground clearance has not been an issue. Like others have said, just take it slow when you see dips or bumps. The lowest point is at the bottom of the canisters, but Tony said he has gotten it 5/8" higher than stock.
