Oh wow, look at that cat! I feel sorry for the stock turbo, and I know what my first mod would be! I'm fairly certain that the slight amount of lag that some of the reviews mentioned would completely disappear with a good high-flowing catless 02 housing/turbine outlet/dump tube/elbow/whatever you wanna call it. I haven't seen the stock dp, but the stock catback doesn't seem to be that well-flowing either, so I would imagine that the gains to be seen from a full 3" turboback would be significant.
Also, I love how direct and straight the FMIC piping is, the location is great. But I wonder why the piping and the FMIC itself seems to bottleneck down compared to both the compressor outlet and the TB? Clearance obviously isn't an issue... I guess Hyundai was just throwing the aftermarket a bone by giving us something else fairly obvious to upgrade, ha.
