The header that started it all! PLM B-Series Tri-Y Big Tube Header has been one of the best selling, best performing header for over 10+ years.

PLM Private Label Mfg. B-Series Tri-Y Big Tube B20 header features a true step up exhaust header design. The Tri-Y header delivers low to mid range power while utilizing a two-piece design.

This header is a long tube design that eliminates your catalytic (cat) converter and is ideal for all forms of competition; auto-cross, drag racing and road racing.

We recommend using a test pipe for easier installation of B-Series headers.
Recommended for high compression 1.8L and 2.0L+ engine displacements.

This header is not compatible with A/C in stock factory setup. That said, we have seen setups with slim fan and AC line adjustments so that the header can work with A/C with these modifications.
