The HEDMAN 39490 is a mid-length short tube exhaust header built for 1985-1988 Toyota 2WD and 4WD pickups running the 22REC fuel-injected 2.4L engine. It replaces the restrictive factory cast manifold with a tubular design that improves exhaust scavenging and frees up power across the rev range. This is the header Toyota truck owners reach for when they're rebuilding or upgrading the breathing on the 22RE platform. It bolts to trucks with air conditioning, floor-shift automatics, and floor-shift manuals. Note that it is not compatible with column-shift manual transmission configurations, so confirm your setup before ordering.
Primary tubes measure 1-1/2 inch in diameter and feed into a 2-1/2 inch ball-and-socket collector, a gasketless joint that seals against the exhaust pipe without a flange gasket to blow out. The kit ships with reducer adapters that step the collector outlet down to 2 inch, matching common 22RE exhaust system diameters. Construction is uncoated mild steel, shipped with a temporary paint coat that burns off during break-in, so plan to wrap or coat the tubes if you want lasting heat and corrosion control. The package includes the header, header gaskets, the reducers, and the header and collector bolts needed for installation. Overall footprint runs 22.30 inches long, 13.70 inches wide, and 8.70 inches tall. Built in the United States and backed by HEDMAN's limited lifetime warranty.
This header suits Toyota pickup owners building a trail rig or a higher-output street-strip truck where stock manifold flow becomes the bottleneck. Pair it with a matching 2 inch exhaust run and a free-flowing muffler to get the full benefit of the improved scavenging. Keep in mind it is rated for off-road use only and not legal for street use on 1975 or later model years, so it belongs on a dedicated trail or competition vehicle. Browse the rest of our headers selection, or round out the build with a muffler and the pipe reducers needed to tie everything together.
It fits 1985-1988 Toyota 2WD and 4WD pickups equipped with the 22REC fuel-injected 2.4L engine. It works with air conditioning, floor-shift automatics, and floor-shift manuals. It does not fit trucks with a column-shift manual transmission, so verify your configuration before ordering.
No. Per HEDMAN's emissions notes, this header is not legal for street use on 1975 or later model years and is intended for off-road use only. It belongs on a dedicated trail or competition vehicle rather than a registered street truck.
The 2-1/2 inch collector includes reducer adapters that step the outlet down to 2 inch. That matches common 22RE exhaust system diameters, so a 2 inch exhaust run pairs directly with the included reducers.
No. It ships as uncoated mild steel with a temporary paint coat that burns off during the first heat cycles. Many owners wrap or apply a high-heat coating afterward for longer-term heat management and corrosion resistance.
The package includes the header, header gaskets, the reducer exhaust adapters, and the header and collector bolts needed for installation.
