Performance Welding uses the finest materials in the industry. We primarily use 18 gauge .049 tubing in either mild steel or 304 stainless steel. Our exhaust flanges are either CNC laser cut cold rolled steel or CNC machined cold rolled steel in 5/16" thick or 3/8", depending on availability for the particular exhaust port configuration.

Our merged collectors are installed using lightweight spring tabs and zinc coated collector springs. This allows the collector to move during the extreme tire shake a high horsepower race car can make, and allows simple removal of the collector.

Our primary tubes are welded on the backside of the flange, then surface ground for a leak-free fit. The outside of the primary tube is tig welded using a silicone bronze filler rod on the top and bottom of the port. This allows the tube to flex in the exhaust flange, if needed and not crack the primary tube. The primary tubes are perfectly butted together at the tube joints, which enables us to make a very small weld beads with very little to no penetration. This allows nothing to obstruct the flow of the inside of the primary tube.

Our stainless steel headers are purge tig welded. This is a must when constructing a stainless steel header, or the primary tubes will have a significant amount of penetration that will obstruct the flow of the exhaust gasses. This is a very unfortunate and time-consuming problem that must be addressed in a stainless header.

All primary tube entrances at the exhaust flange, from the exhaust port exit, are fully deburred and radiused for a nice smooth transition, making sure not to shroud the cylinder head exhaust port.

Our excellent header construction techniques allow us to provide you with the finest profesional competition racing header in the industry. Our superb tig welding and the quality of our materials allow us to give you a two-year craftsmanship warranty from date of purchase.
