Maybe one of our Dealer Tech's or J.K. or somebody out there might know the answer to this.If you remember the left side exhaust manifolds had the dimmple/restriction cast into them to clear the steering shafts in the early K series trucks ? This is when they were developing and testing the D/max in the 1999-2000 truck bodies ? Prior to production and placement into the new 2001 bodies of which they were designed to go in. Any way I know my 07 still had the original left side restricted manifold in it. they just never changed the casting and produced the same part even though the clearence wasn't an issue in the new body style. As most of you know there is an aftermarket manifold available that doesn't have the restriction in it. I was wondering if anyone know's if the new LML engine finally got a new unresticted manifold, or do they still run the same one's as previous years? Thanks.
