Duramax Drivers Side Exhaust Manifold Removal

And ill be doing a lml drivers side.

Duramax drivers side exhaust manifold removal.

Inner fender liner has to be removed to access driver s side of the duramax. Afe bladerunner iron exhaust manifolds 01 16 gm 6 6l duramax afe 46 40024 26 00 afe 46 40024. I ended up snapping a bolt in the manifold and figure ill take it off to drill it out. The increased flow will balance the engine and provide increased spool up throttle response and better overall performance.

This high flow manifold flows better than the original drivers side manifold by offering less restriction to match passenger side manifold flow. The xd342 has an unrestricted high flow design that eliminates the dented or kinked driver side exhaust manifold that comes factory equipped on the 2001 2010 gm 6 6l duramax powered trucks. The gm 12637647 updated driver side exhaust manifold for your 2001 2016 gm 6 6l duramax features a full bore unlike the factory exhaust manifold that is kinked or dented for additional clearance. Replace the exhaust manifold in your 2001 2016 gm 6 6l duramax with the xdp driver side high flow exhaust manifold xd342.

They were a huge pain. Im starting to dissemble my truck for my s472 to go on. You may not know it but the factory driver s side exhaust manifold is pinched down to allow for steering shaft clearance which actually isn t required. I got the up pipe bolts on the turbo and the passenger side up pipe to manifold bolts off.

As a result this manifold only flows 80 compared to the passenger side. Doing the r r is easy except for the rear bolts at the exhaust flange which are hard to reach and remove.
