Description
Ramjet VT–VZ Triple-Step Headers
GM Motorsport have taken header design to the next level with a true long-tube, equal-length system that still fits within a compact space. Unlike anything else on the market, these headers feature extended rear primaries and a triple-stepped design — 1 ¾" to 1 ⅞" to 2" — maximising exhaust velocity for superior flow and pulse balance across all cylinders.
The result? Maximum torque, sharper scavenging, and an aggressive yet refined note that only equal-length, stepped headers can deliver. Built from premium 304 stainless steel, these headers are engineered to withstand extreme heat while offering unmatched durability.
If you’re chasing precision engineering with real-world performance gains, the Ramjet Triple-Step 1 ¾" headers are the ultimate upgrade.
Note – Some clearancing may be required for these headers.
