Best Headers for 2009-2018 Ram 1500 5.7L Hemi: 2026 Guide

If you own a 2009-2018 Ram 1500 with the 5.7L Hemi, you already know it makes a great noise and pulls hard — but those restrictive cast-iron exhaust manifolds are leaving torque and a few horsepower on the table. Swapping them for the best headers for the 2009-2018 Ram 1500 5.7L Hemi is one of the most popular bolt-on upgrades we ship out of our Tampa, FL shop, and for good reason. A quality set of shorty headers wakes up the mid-range, sharpens throttle response, frees up a deeper Hemi growl, and permanently cures the dreaded “Hemi tick” exhaust leak. In this guide we compare three kits we actually stock — from a value-leading BBK set to a premium USA-made Kooks system — with honest real-world numbers, the install reality, and the legal fine print most pages skip.

Why Add Headers to Your 5.7L Hemi Ram?

Headers replace the factory cast-iron exhaust manifolds with smooth, mandrel-bent tubes that let each cylinder breathe more freely on the exhaust stroke. On a naturally aspirated 5.7L Hemi, the payoff is not a huge peak-horsepower number — it is fatter mid-range torque right where a truck lives. Most owners feel sharper throttle response from 2,000 to 4,000 RPM, exactly the range you use merging, passing, and towing.

There is a second, often bigger reason Ram owners pull the trigger: the Hemi tick. The factory manifolds on these trucks are notorious for warping and snapping their bolts, which opens an exhaust leak and produces a metallic ticking at idle and under load. A fresh set of headers with thick 3/8 in flanges and new hardware seals that leak permanently — so you fix a known weak point and add power in the same afternoon. You also get a deeper, more defined Hemi note without the drone of a straight-pipe.

Shorty vs. Long-Tube Headers: Which Is Right for a Daily-Driven Ram?

Shorty (or tuned-length) headers have short primaries that end at the factory manifold flange — they bolt right where the cast manifold was, so your factory Y-pipe, catalytic converters, and oxygen sensors all stay in their original spots. Long-tube headers run much longer primaries into a collector farther downstream, which relocates the cats and requires a new mid-pipe.

For a street-driven or towing Ram 1500, shorty headers are the smarter pick, and it is what we recommend to the vast majority of customers:

• No tune required. Because the cats stay in their factory location, the ECU keeps fueling correctly and you typically will not throw a check-engine light.
• Easier, cheaper install. They work with the factory mid-pipe and O2 wiring — no cutting or welding.
• Torque where you drive. The gains land in the 2,000-4,000 RPM mid-range instead of way up high.
• Easier to keep legal. Keeping the cats in place is what makes shorties street-legal in most states (more on California below).

Long-tubes can make 25-35+ wheel horsepower, but they demand a tune, move the cats, and are off-limits in California and other CARB states. For a daily Hemi, the shorty trade-off is the right one — which is why all three of our picks are tuned-length shorty kits.

The Best Headers for the 2009-2018 Ram 1500 5.7L Hemi

All three kits below are direct bolt-on, tuned-length shorty headers that fit the 2009-2018 Ram 1500 5.7L Hemi (and the 2019-2024 Ram 1500 Classic). They retain the factory catalytic converters and oxygen-sensor locations, and each ships with new gaskets and hardware in the box. They differ in material, finish, claimed gains, and price.

1. BBK 1-3/4 in Titanium Ceramic Shorty Headers — Best Overall Value

This is the kit on most of our customers' Rams, and it is our top pick for one simple reason: it is the most header for the money. BBK has built bolt-on performance parts since 1988, and these 1-3/4 in tuned-length headers use CNC mandrel-bent tubing with thick 3/8 in flanges and a titanium-ceramic coating that holds in heat and trims under-hood temps. BBK rates them at roughly 15 horsepower and torque over stock. They bolt to your factory mid-pipe, reuse the stock oxygen sensors, and include new gaskets and hardware. Curiously, this titanium finish is priced below the polished-silver version of the exact same header — so you get the same performance for less.

2. BBK 1-3/4 in Silver Ceramic Shorty Headers — Best Show Finish

Mechanically, this header is identical to our top pick — same 1-3/4 in tuned-length design, same 3/8 in flanges, same fitment and gains. The difference is the finish: a bright, double-ceramic polished-silver coating that looks fantastic in an engine bay you actually pop the hood on at shows and meets. If appearance matters more to you than saving roughly seventy bucks, this is the one to get. Just know you are paying for the finish, not extra power.

3. Kooks 1-5/8 in Stainless Torque Series Shorty Headers — Premium Pick

When you want the no-compromise build, Kooks is the answer. The Torque Series uses a stepped primary design — starting at 1-5/8 in and stepping up to 1-3/4 in — that is tuned to maximize low and mid-range torque, ideal for a truck. They are built from heavy 16-gauge 304 stainless steel with 3/8 in CNC D-port flanges, handcrafted in the USA, and backed by Kooks' lifetime warranty against manufacturing defects. Kooks claims up to 25 horsepower and 40 lb-ft of torque (a best-case figure that typically assumes supporting mods). They are built to order, so plan for a lead time. The catch is price: roughly five times the BBK kits. For most owners the BBK is the value play, but if you keep your trucks for the long haul, the stainless Kooks set is a buy-it-once upgrade.

Ram 1500 Hemi Header Comparison: Side by Side

Here is how the three shorty-header kits stack up at a glance. All fit the 2009-2018 Ram 1500 5.7L Hemi, retain the factory catalytic converters, and require no tune.

How Much Horsepower Do Headers Add to a 5.7 Hemi?

Here is the honest answer most pages dodge: on a stock-tuned 5.7L Hemi, shorty headers alone typically add about 8-15 wheel horsepower, plus roughly 15-20 lb-ft of mid-range torque. Manufacturer claims run higher — BBK lists around 15 HP, Kooks up to 25 HP and 40 lb-ft — but those are best-case numbers that usually assume supporting modifications. We would rather you buy with realistic expectations.

The takeaway: do not chase a giant peak-horsepower figure. The value of headers on a Hemi is sharper throttle response, a meatier mid-range you feel every day, a better exhaust note, and sealing the manifold leak. Headers also breathe best as part of a system. Pair them with a cold-air intake and a cat-back exhaust so the engine can inhale and exhale freely, and add a custom tune to optimize the air-fuel ratio and squeeze out the rest. A tune is optional with shorties (the factory cats stay put, so no check-engine light in the vast majority of cases) but it is the finishing move on a full bolt-on build. Do not expect a meaningful MPG change — that is not what headers are for.

Installing Shorty Headers on Your Ram 1500

Shorty header installs are rated about average difficulty. BBK quotes roughly two hours for a clean job, and a shop will usually bill two to four hours of labor. In the real world, the time you spend depends almost entirely on one thing: bolts. The same rusted, seized, or already-broken manifold bolts that cause the Hemi tick are the biggest variable in a header swap.

A few things to know before you start:

• Soak the hardware early. Hit the manifold bolts with penetrating oil ahead of time. If a stud snaps, you will need an extractor (or to weld a nut on), so budget time for it.
• Driver-side access. You will typically unbolt and move the steering shaft aside, and the engine often has to be raised slightly for clearance.
• O2 sensors. Unplug the oxygen-sensor connectors at the mid-pipe; a dab of anti-seize on the threads (never the tip) makes the next job easier.
• Re-torque after heat cycles. Tighten the header bolts evenly in sequence, then re-torque them after a few heat cycles and a few hundred miles to prevent a gasket leak. New gaskets and hardware come in the box with all three kits.
• Do not wrap them. Note that adding header wrap voids the BBK warranty.

If you are mechanically inclined with a lift or jack stands, this is a satisfying weekend job. If your truck lives in the rust belt or has high miles, having a shop handle the broken-bolt risk is money well spent. Driving an earlier truck?

Are These Headers Legal in My State?

This is the fine print that matters. All three of these kits are not CARB certified, which means we cannot ship them to California or to other states that have adopted California emissions standards. If you live in California, these are not a legal option for a street-registered vehicle — they would fail a Smog Check, and we are not able to ship to a CA address.

For buyers in the other 49 states, shorty headers are generally street-legal because they keep the factory catalytic converters in their original location. That said, emissions rules vary by state and locality, so you are responsible for confirming the law where you live. These products also carry a California Proposition 65 warning. If you must have a CARB-certified, 50-state-legal header, there are emissions-exempt shorty options on the market with an EO number — just note those are outside the three kits we stock and compare here. When in doubt, give our Tampa team a call and we will help you sort out what is right for your truck and your state.
