2005 Dodge Ram 3500 5.9L QCLB I like the product and fitment, went in nicely and works very well. 🤙 BUT…. the BD bolt kit was a disaster, 10mm bolts with spacers having a 9.5mm diameter, hmmm 🤔 ohhh simple math tells me it won’t fit 🤷♂️🤓🤣 Quality Control????

    • BD Diesel quality. Amazon value.
This was a ‘while I’m at it’ upgrade. I was upgrading my turbo, cam, studs and injectors with 213K on the odo. So rather than drilling another hole for a second pyro probe (already had one for my Banks water injectors) for a pyro gauge, I might as well improve my reliability with a 2 piece manifold with its added performance flow and it already pre-drilled for 2 probes. ... show more

Install was straight forward and the manifold looks pretty beefy. Will see how well it holds up over time but I am very impressed with this one over the cheaply stock manifold. Wish they would include studs and gaskets with the amount of money you’re paying for this manifold.

    • Awesome replacement for the OEM manifold.
Easy installation, excellent product quality. Noticed towing improvement on hill climbs over OEM manifold. well worth the price and an excellent improvement/enhancement over the stock 06 Dodge Cummins 5.9L manifold. FYI, if you're gonna take the time to replace the exhaust manifold, you might want to consider replacing the manifold bolts with ARP studs. The OEM bolts will break as well as the OEM manifold is prone to cracking. This is an excellent product and I recommend to all 06 Dodge Cummins owners. ... show more

    • Bought used looks new
Had to fix some dings where the manifold pieces seal together but other than that it was $132 off new price....well worth the chance I took! (Edit after install) Not impressed with clearances made for the bolts or studs. Way too tight of clearances and makes for not a fun time. Everywhere but mainly where the coolant hose bracket attaches. Had to get inventive and reuse spacer and bolt to even come close. ... show more

    • It was not machined correctly
So this was not machined correctly andnthe two pieces did not fit together. Called BD up and they don't warranty their products if sold through Amazon. A great company stands behind their product regardless of who the seller is.
