It set me back almost $500...mostly because of the chrome plating. I did not have to get it done, but it just looks much better. One person asked me about the heat soak...its not bad at all. I Just put it in today and drove it around alot. I live in Pleasanton, it gets pretty hot here. When at a stand still, ya it gets warm. But once i start going, the difference is huge. All in All, the heat soak is about the same as the Lingenfelter, but the performance is better throughout the power band.
