actually i've had an eibach pro kit on kyb's. it was comfortable, but still 4x4 for a teg....i ditched to pro kit and put some shorter springs on the kyb's and it was bouncy as fuck. ive road in a couple cars with full skunk2 suspension, and its still bouncy compared to stock ride hight. and far as the exhaust goes, it was on the car when i bought it.
