BD-Power Duramax Exhaust Manifold 1041460

bought this for the pyrometer hole, wrks great all day job for sure.

i purchased this when replacing the heads on my truck and now with this on, it greatly reduced my egt's and i also replaced the turbo down pipe with mbrp's 4in. downpipe to go with my custom 4in. exhaust. thanks xdp

I upgraded my total exhuast system prior to deploying to Iraq. I noticed that my engine had a slight surge while at idle afterwards. After researching the problem I discovered that replacement of the stock driver side exhuast manifold was a must. I purchased this product while deployed, XDP thanks, and two things happen. One...the engine surge went away. Two the truck has more throttle responsive and more power either at towing or daily drive. Installment took 1 hour. Great product here offered by a great company. Thanks XDP.

its not a bad buy for the money i beleive its all worth it just for the perfect egt probe placement no power difference with this but motor seamed to idle alot better

I like the quality and workmanship. It installed with no messing with bolt holds. I did not notice anything special with performance but I do not have anything unusal on the engine. The old manifold was really restricted conpare to BD manifold. I would get another for my next vechile.

Takes 2 to 3 hours to install in the driveway. I'm a certified automotive technician and this was the best exhaust upgrade for the dollar. Then you remove the O.E. manifold and look at the new one you'll under stand why this is a must have! The diesel even sounds more balanced.
