Replace your restrictive OEM cast exhaust manifold with our high flowing tubular model. Made from thick walled 304 stainless steel tubing, this manifold is an exact replacement for the stock unit and no other modifications are required. Features near equal length runners with multi-pass TIG welded joints. All flanges are CNC machined from 1/2″ 304 stainless steel and surfaced to ensure a leak free seal. The ports are gasket matched and smoothed to perfection for the best of flow! Power gains can be expected throughout the entire RPM band.
