The HP gain on even a highly modified engine are minimal. There can be some benefit from less heat under the hood but that has nothing to do with performance unless it reduced the temp of the air going into the engine. The downside are the claims that other than on stainless headers the wrap promotes rust. If you want to keep more of the heat inside you could spray the headers with ceramic header paint. Instead I would find out the best way to increase HP without losing any torque from other 3.0 owners. My guess would be reducing the exhaust back pressure some would be the best return on investment.
