If you've started noticing a loud ticking sound coming from your engine bay every morning, you're likely in the market for a 2019 ram 1500 exhaust manifold kit to fix the problem. It's a frustratingly common issue for Ram owners, particularly those with the 5.7L Hemi engine. That "Hemi tick" isn't always the valves or lifters; more often than not, it's a warped manifold or a snapped manifold bolt. It starts as a minor annoyance that disappears once the engine warms up, but if you let it go, it can lead to bigger performance issues and even damage to your cylinder heads.
Why Do These Manifolds Fail So Often?
It's the question every Ram owner asks eventually. Why does a relatively modern truck have such a persistent exhaust issue? The heart of the problem lies in the metallurgy. The factory exhaust manifolds are made of cast iron, while the cylinder heads they're bolted to are made of aluminum.
When you drive, these two metals heat up and expand at completely different rates. Over thousands of heat cycles, that physical stress has to go somewhere. Usually, the manifold starts to warp or "curl" at the ends. Since the bolts holding it in place are made of steel, they eventually reach their breaking point. Most of the time, it's the rear-most bolts (closest to the firewall) that snap off. Once that bolt head flies off, the seal is broken, and you've got an exhaust leak. That's the ticking sound you're hearing—it's high-pressure exhaust gas escaping through a tiny gap.
What Comes in a 2019 Ram 1500 Exhaust Manifold Kit?
When you go shopping for a 2019 ram 1500 exhaust manifold kit, you'll find that the contents can vary depending on whether you're buying a budget-friendly replacement or a heavy-duty upgrade. Generally, a complete kit should include:
- The exhaust manifold itself (either driver or passenger side).
- A high-quality multi-layer steel (MLS) gasket.
- A full set of mounting bolts or studs.
- The heat shield (though sometimes you can reuse your old one).
I always tell people not to skimp on the hardware. If the kit you're looking at comes with cheap, generic bolts, you're just asking for a repeat performance of the same problem in another 30,000 miles. Look for kits that include Grade 8 hardware or, even better, stainless steel studs that can handle the heat cycling without getting brittle.
Choosing Between OEM and Aftermarket Kits
This is where the debate gets interesting. If you go to a dealership, they're going to want to put an OEM (Original Equipment Manufacturer) kit back on your truck. While that sounds like the "safe" bet, remember that the OEM design is what failed in the first place.
The Case for Aftermarket Kits
Many aftermarket companies have actually improved on the original design. Some brands, like Dorman or BD Diesel, offer manifolds that are cast thicker or made from different alloys that are less prone to warping. Some even have "slotted" bolt holes that allow for a tiny bit of movement as the metal expands, which takes the pressure off the bolts. If you're planning on keeping your truck for the long haul, an upgraded aftermarket 2019 ram 1500 exhaust manifold kit is usually the way to go.
The Budget Route
If you're just trying to get the truck back on the road without spending a fortune, there are plenty of entry-level kits available. These are great for a quick fix, but just keep in mind that the labor to change these out is the real killer. It's often worth spending an extra $50 or $100 on a premium kit so you don't have to pay a mechanic $600 to do the job all over again next year.
Can You Handle the Install Yourself?
I'll be honest with you: replacing an exhaust manifold on a 2019 Ram 1500 is not a job for the faint of heart. If it were just a matter of unbolting the old one and slapping the new one on, it would be a "Saturday afternoon and a six-pack" kind of job. But it's never that simple.
The real nightmare is the broken bolts. Remember how I mentioned the bolts usually snap off? Well, they often snap off flush with the cylinder head or even slightly inside the hole. This means you'll be spending hours with a drill, an extractor kit, and a whole lot of patience trying to get those remnants out without damaging the threads in your expensive aluminum heads.
If you have a solid set of tools, including a good torque wrench and some high-quality drill bits, you can definitely do it. But if the thought of drilling into your engine block makes you sweat, you might want to hand this one over to a professional.
The Performance Upgrade: Headers vs. Manifolds
While you're looking for a 2019 ram 1500 exhaust manifold kit, you might notice that "Shorty Headers" often pop up in the search results. This is a popular alternative for a lot of Ram owners.
Headers are made of tubing rather than a single cast piece. Because they're thinner and designed differently, they dissipate heat much faster and generally don't warp like the stock cast-iron pieces. Plus, they usually offer a slight bump in horsepower and a deeper, throatier exhaust note.
The downside? They can be a bit more expensive, and the installation can be even tighter in the cramped engine bay of the 5th Gen Ram. However, many owners swear by them as a "permanent" fix for the manifold issue. If you're going to spend the money anyway, it's a solid option to consider.
Important Features to Look For
When you're scrolling through parts sites, don't just click the cheapest option. Here are a few things to keep an eye out for in a quality 2019 ram 1500 exhaust manifold kit:
- Reinforced Casting: Look for descriptions that mention extra material around the bolt flanges. This helps prevent the manifold from "curling" as it ages.
- Coated Finishes: Some kits come with a ceramic coating or a high-temp paint. This isn't just for looks; it helps with heat management and prevents the manifold from rusting out over time.
- Correct Fitment: 2019 was a "split" year for Ram. There's the "Classic" (DS) model and the "New Body Style" (DT). Make sure the kit you buy is specifically designed for your version, as the clearances can be slightly different.
What About the Passenger Side?
Interestingly, the passenger side manifold seems to fail more frequently than the driver's side on these trucks. This is mostly due to the way heat builds up on that side of the engine bay and the way the exhaust is routed. If you're changing one side because of a leak, many mechanics will suggest doing both at once.
It sounds like a lot of extra work, but the logic is sound: if one side has already failed, the other side is probably right behind it. Buying a dual-side 2019 ram 1500 exhaust manifold kit can save you a second trip to the shop (and a second labor bill) six months down the road.
Final Thoughts on Maintenance
Once you've got your new kit installed, there are a few things you can do to make it last. First, always make sure your engine is properly tuned. A truck that's running too lean will produce much higher exhaust gas temperatures (EGTs), which puts way more stress on those manifolds.
Also, try to avoid "heat soaking" the truck and then immediately shutting it off after a heavy tow. Letting the engine idle for a minute or two after a long, hot haul allows the oil and coolant to circulate and helps the manifolds cool down more gradually. It might sound like overkill, but when you've spent the time and money on a fresh 2019 ram 1500 exhaust manifold kit, you'll want to do everything you can to keep that Hemi tick away for good.
Fixing an exhaust leak isn't the most glamorous project, but the peace of mind you get from a quiet, efficient engine is worth every penny. No more embarrassing ticking at the drive-thru, no more lost MPGs, and no more worrying about those snapped bolts. Get the right kit, do it once, and do it right.
