BD Diesel 1045947 Exhaust Manifold

I've installed these bd exhaust manifolds on trucks numerous of times and never had any fitment issues or defects.

I installed a BD-Power Exhaust Pulse Manifold on my 2002 RAM 2500 HO 6spd. I have a stock HX35 turbo. I am so far satisfied with the manifold and have seen a quicker mid-range turbo spool up (after 5psi, it increases rapidly to max). I have also noted about 60 - 100 degree F less EGT. I was a little disappointed in that you only receive two of the stainless cap head bolts (and washers) for the manifold instead of the 12 that are depicted in the photo (you will reuse the stock bolts). You also get two stainless cap head bolts (and washers) for the turbo housing which replaces two nuts. I was unable to install the manifold exactly per the directions since I could not remove the lower aft nut from the turbo housing/manifold flange with the turbo still in the engine compartment as described in the installation directions. The nut is located in a recess on the turbo housing under the wastegate stem and was too tight to remove with an open end wrench (the only thing I could get on the nut). I instead had to remove the turbo and the manifold as an assembly and dismantle on the workbench. This was not a huge undertaking; however, it was not exactly per the procedure. Overall, this is a pretty good product for the money.

just added my new bd-manifold..on my 03 dodge, it made a big power change than stock, lowerd my egts by about 100-200 degress. good work bd!!!!

I just had this installed on my truck, and I love it. I immediately noticed quicker turbo spool, better acceleration, and lower EGT's. I used to have to wait a long time for the EGT's to cool down to save the turbo, now it cools down to around 300 degrees in a matter of a few seconds instead of close to a minute or more in the heat. On the freeway the AVG Econ went up to 19+ right away. I also noticed that it smokes less. I have an 06 5.9 with a Smarty, and intake and exhaust.

It took twice as long to remove the stock manifold then to install this item. Fit was perfect and I recieved all the hardware decribed. The only thing you reuse is two of the studs off of your turbo mounts to the manifold. This acually makes it easier to install. Just pop them out with vice grips. Also used the BD gaskets and there's no leaks. Pyro guage fit perfectly in the pre-tapped port. Looks great, runs great.

You get what you pay for. It looks almost identical to the ATS manifold, and I think its better because of the EGT probe location. The BD has a better one, as compared to the ats. The installation was a bit tricky (took 6 hours), but I got held up putting the #5 cylinder bottom side bolt in. Removing the turbo is a must, I thought that you could just keep it on, but there is no way to do it without taking the turbo off. Anyways, I could definitely feel a performance difference. And my stock turbo spooled much faster. It even lowered the tone of the exhaust, and made it where you can more distinctly hear each cylinder fire. All and all, its a great manifold, and I would recommend it to anyone.
