Here's a few of my JBA EVOL catback since I didn't see any JBA's on here yet.
My performance mods are the JBA EVOL, hybrid S&B CAI and timing advance.
Here is idle and rev in park (from inside the cab):
Idle and rev in park (outside the vehicle):
Accelerating on the highway:
Accelerating 5-55 mph (pretty much WOT):
My air intake accounds for some of the noise in the cab, but the exhaust sound does overpower it. I don't like the tapping sound on the rev in PARK. Luckily it is only noticable in the cab if you have the rear window down and at WOT; if the windows aren't down you don't hear it. Also not noticable in the videos is that there is some drone at the normal 1600-1800 rpm range under part- throttle and under load. I don't think it is that bad though.
