Your cart is empty.Experience unparalleled performance and durability with our enhanced Dodge/RAM truck exhaust manifolds, specifically designed for 5.7L HEMI engines. Our BD upgraded manifolds address common exhaust manifold bolt failures by incorporating extended fasteners and spacers that effectively withstand thermal expansion. In addition, we've engineered independent mounting locations for the heat shield, separating it from the mounting bolts to further enhance reliability. Crafted with precision, our BD Manifolds boast a robust, thicker design, and are constructed from high-silicon ductile iron to combat warping, ensuring your vehicle remains at peak performance for the long haul.

Great product. Got rid of the hemi tick right away. Perfect fit on my ‘14 Ram 5.7.

I installed these on my 2018 RAM1500 Sport. Perfect fit and so much thicker walled than the originals.No modifications needed, but I did need to order the heat shields (from Rock Auto) for another $40. They expect your old ones to be usable, but how often does that happen?For the price, they should include the heat shields. Other than that little disappointment, these manifolds are the best around and I do highly recommend them!If you own a RAM, you will be replacing your exhaust manifolds every 50k - 100k using OEM parts and I am hoping these last at least twice as long.

My mechanic recommended this exhaust manifold kit for my 2013 Ram 1500 5.7 Hemi. When I ordered, it arrived as promised the next day. The manifolds are heavier and thicker than the OEM ones that came with the vehicle when I bought it new. They should be more durable as well. They fit like a glove. So far so good after the first month the kit was installed.

I used these to replace the junk BBK headers that only lasted a year before they cracked And rusted, these were an excellent replacement choice. The installation went very smooth, And as an engineer, I can appreciate how robust the castings are compared to the OEM and other cheap aftermarket options. The only thing I would add Our heat shields, as by this point if you are already replacing the headers, you’re OEM heat shields are probably destroyed by now.

With broken studs in the head, the labor was 7.5 hours. The product fit was fine, I hope this solves the unacceptable neglect by Chrysler Corp. According to internet reports, this has been a major problem since 2012. I am hoping that BD did a better job. The orginal packaging was open, but Amazon shipped in another box which was not damaged.

Had 5 total broken bolts on the shitty OEM once.Had this installed, tech told me fitment was excellent, the kit have all you need to perform the repair, seem to be of very good quality. After installation the truck got quiet again, no more damn tick tick tick.Getting better MPG, cleared my P0420 code and check engine light.Driven the truck 1,200 miles and so far loving it. Truck sounds like a new truck again.If your RAM 1500 ticks, don't bother with the OEM crap, it will brake again on no time.I hope this holds on for more than lousy 20,000 miles, especially for how much it cost in labor to have the broken bolts extract.

This thing went on slicker than dog stuff. Perfect fit, lot better quality over oem. Only snag I had it could be my fault but not all the holes in the exhaust gasket were punched out. Hence put it on had all bolts in but one and it didn’t want to go in. Had to take back off. Other than that can’t speak highly enough

Extreme pain to install, but doable if you're used to wrenching on vehicles. Update March 10. Manifolds were installed in November, passenger side gasket blew out in January. Just got around to changing gasket, replacing with remflex 6022.

This item looks like it is made well but it does NOT fit for 2019 and newer 5.7 gas engines
