PLM RF V2 4-1 Megaphone Narrow Header & Test Pipe - B-series

PLM Power Driven RF B-series RF V2 4-1 narrow header megaphone features a true 4-1 merge to create equal exhaust flow. This header delivers the best peak horsepower gains while utilizing a 1-piece design.  The narrow design creates better clearances for supercharger fitment or other accessories. Knowing this is an aftermarket header, the length may differ compared to your stock OEM exhaust manifold. Includes straight pipe, gaskets, and mounting hardware. This header is ideal for all forms of competition: autocross, drag racing, and road racing.

PLM recommends using their included test pipes for easier installation of B-series headers.
