More power from your B-series engine with SRS manifold 4-1 2.5 inch stainless steel

Do you really want to get the most out of your B-series engine? Then choose the SRS manifold 4-1 2.5 inch stainless steel. A 4-1 manifold delivers maximum power gain at high rpm, and certainly in combination with the 2.5 inch connection.

4-1 = Maximum power gain at high rpm

Including connection 2 lambda sensors

2.5" cat replacement / test pipe needed for assembly

The thicker diameter of this manifold ensures that it cant be mounted with the original catalyst. For optimal performance, order an SRS cat replacement or test pipe with 2.5" connection.
Furthermore, the SRS 4-1 2.5 inch manifold is delivered including all fasteners such as gaskets, bolts and nuts.
