I wouldn't claim anything unless there is dyno proof. Is there a dyno plot somewhere?

It just SOUNDS like 15 horse. In the summer time, it's like minus 20 HP.

You have to decide if it's worth it just for the sound. It takes about 20 HP to really be able to discern the difference. I didn't get that much. BUT---the sound is lovely.

Actually KKM claims 8-12 HP increase but mileage may vary from car to car. My dyno shows about a 25-30 HP increase with the KKM, Intake Tube and Magnaflow. Of course, that was compared to a stock 03 LS which boasts an additional 28 HP increase over a stock 00-02 LS.

I can tell you I was not a believer in them for the price, but I got a used one and put it on my car and was surprised. At the time when my LS was stock I used my G-tech and made 3 runs on a stright level road, and got a best of 15.2, about 2 weeks later after doing exhaust and the KMM I made 3 passes at the same place and got a best of 14.2. Now I dont think my car does 14.2, but using the same G-tech and same road, and roughly same ambient temp there was deff. a difference.
