International Navistar (Harvester) MaxxForce DT – DT466 diesel pulling tractor headers from GP Headers are built in the USA, run and tested by experts in the DT466 world. These diesels are known to make big power but to reliably put down the needed power for your supporting mods we have designed this exhaust manifold that is TIG welded / back purged and Hand fabricated with American 304 stainless steel. This set is for a International DT466 engine running a T6 framed turbo. Knowing the abuse these manifolds take they are built using a full .5” thick flange that is welded on both sides and braced between the flanges to help hold the weight. The primary tubes use double slip joints to help eliminate any thermal stress cracks by allowing each section to expand freely while still sealing the added back pressure from the turbo. EGT sensor bungs come standard on this manifold. No more second guessing if you have the correct manifold for your pulling project. This International DT466 turbo pulling tractor manifold is the absolute best start to laying down serious power for your award winning pulling machine.
