Part two of the FD2/FG2 comparo. This time it's Taniguchi giving his impressions. Got tired of Windows Movie Maker freezing up, so translated only the Si portion
Apex'i World Sport 2 (WS2) catback exhaust on an otherwise stock 2006 Civic Si coupe (FG2). Start, idle, outside WOT, in-car WOT cruise.
Quick review: When driving I can't hear the exhaust at WOT, but it's discernable at 3-4k RPM.
The in-car WOT sound is shoddy because I made the mistake of driving on a twisty road--hence all the microphone interference.
