How they took a stock 03 Cobra and added a few mods to her and presto! 400 rwhp. Pretty cool I think but more interesting was the gain in HP when the exhaust mods were installed they added a very large cone filter setup sans silencer which gave them a 17(I think) HP gain. I would definitely love to get that from a filter replacement. Clicking around www.volantperformance.com kinda got me pumped to do some custom stuff with bits and pieces from different sites. We'll see.
