Performance Welding Racing Headers now has Merged 4 - 2 - 1 Collectors kits to compliment our line of Exhaust products.

These collectors are hand built to your Competition engines requirements using the finest materials in the industry. These collectors have shown an increase in performance and are an excellent tuning aid to maximize the volumetric effiency from your combination. They are an excellent collector choice in all forms of racing and are sold in a compete kit form including six two into one Merged Collectors, collector springs and tabs, an additional 4"straight tube length tubing for fine tuning on the dyno or the racetrack, and a megaphone style outlet.

They are designed to separate the exhaust pulses as per firing order and increase exhaust speed in the collector to pull more air (scavenge) through your competition engine.

Two into one Merged Collectors may be purchased separately, and 4 - 2 - 1 kits may be used as an upgrade on our Competition Racing Headers. Prices below are for V8 applications below in complete kit form as shown.
