Installation was very easy and only took about 1 1/2 hours. Not sure if there is much of a power gain, but the throttle response and acceleration are much quicker and smoother. Also have a K&N intake installed and they work well together. Sounds great at startup and idle as well as while cruising. Definitely the right choice for aggressive, but not obnoxious.
