No matter which of the Acura NSX exhaust headers you buy from AutoAnything today, we promise that the price you pay for any and all of them is the lowest you'll be able to pay for a full year. That's our 1-year lower price guarantee and it means that even if another company is selling the same NSX headers for less than you paid with us, tell us about it and we'll refund you the price difference plus a dollar. We even ship your new NSX headers right to your door, completely free of charge!
