It's no secret that the most horsepower per dollar improvement you can do to your Acura is to replace your stock exhaust manifold with a tuned header system. And a DC Sports dyno tuned and tested header will breathe new life into the performance of your vehicle. This allows you to take full advantage of the power that is all too often hidden away inside your engine. This header is polished with T-304 stainless steel. It is designed to stand up to the harshest condistoins you can subject it to and provide you with the most power from any legal header on the market.
