EMPI Competition Merged Exhaust Header | VW Beetle, Ghia & Type 1 | 1-5/8" Mandrel-Bent, Dual Carb (3699)

EMPI Competition Merged Exhaust System — 1-5/8" Mandrel-Bent Type 1 Header

Built for serious performance. The EMPI Competition Merged Header features 1-5/8" mandrel-bent tubing with a hand-cut and fitted longer collector that maximizes exhaust scavenging and unlocks top-end power. Designed for dual-carb performance builds, this header eliminates heater boxes for maximum airflow.

Comes with a non-baffled black stinger and all the gaskets and hardware needed for the stinger. For a quieter setup, add an EMPI merged-compatible muffler (part numbers 3700, 55-3700, 3701, 3702, or 3703).
