Unlock the full potential of your 1UZ, 2UZ, or 3UZ V8 swap with a set of precision-engineered UZ Swap Headers, specifically designed for the tight Toyota engine bays. These are designed for 1989 - 1995 Pickups and 4Runners. Designed to deliver maximum flow and minimum hassle, these headers offer bolt-on performance, perfect clearance, and exceptional durability for your V8 conversion.
These fabricated headers replace the restrictive OEM UZ manifolds with equal-length, mandrel-bent runners, significantly improving exhaust scavenging, reducing back pressure, and enhancing throttle response.
Each set is specifically designed to tuck cleanly between the frame rail and anti-sway bar, while retaining your factory-style steering linkage. That means no cutting, no smashing, no guesswork — just clean, confident fitment in your rig. We use factory Toyota-style connector gaskets, so spares are easily sourced should you ever need to remove the exhaust.
Note:These headers do not have any provisions for EGR. You will need to either use our EGR Block plate or provision your exhaust to reconnect it if you plan on keeping it.
Beefy 1/2″ flanges at the head + mandrel-bent stainless tubing
Equal-length runners for smooth exhaust pulses
TIG-welded and pressure-tested for leak-free performance
Designed to clear stock steering setups and sway bar
Collector angle optimized for dual or crossover exhaust
