Weapon R Stainless Steel street headers are completely constructed of stainless steel and then polished to a show quality finish. Weapon R performance aftermarket headers increase hosepower and torque and do not sacrifice daily driving.
These Weapon R street headers are second to none, when it comes to WR Racing Headers. Our Flanges are CNC machined and then welded inside and out to prevent cracking. We pride ourselves on our CNC Mendrel Bent tubes which are computer welded.
