Long Tube Headers for the 5.7 Hemi: Exhaust Manifold vs Headers Explained
If you own a 5.7 Hemi, sooner or later you start thinking about the exhaust. The factory system is built to be quiet, cheap to produce and easy to pass emissions with, which is exactly why so many Challenger, Charger and Ram owners look at headers as their first serious upgrade. At Merrick Motorsports in Las Vegas we stock more than 30,000 parts, and questions about long tube headers for the 5.7 Hemi come in almost every week. This guide walks through how headers differ from the stock exhaust manifold, when long tubes make sense versus shorty headers, and which parts in our catalog fit your build.
Exhaust Manifold vs Headers: What Is the Difference?
The exhaust manifold and a set of headers do the same basic job. Both bolt to the cylinder head, collect the exhaust gas leaving each cylinder and route it into the rest of the exhaust system. The difference is in how they do it. A factory exhaust manifold is usually a compact, heavy casting with short, uneven passages that merge quickly. It is designed to fit tightly in a crowded engine bay, warm up the catalytic converters fast and last for the life of the vehicle with little attention.
Headers replace that casting with individual tubes for each cylinder. Those tubes are formed to similar lengths and merge in a collector further downstream. Because each cylinder gets its own path, exhaust pulses are less likely to interfere with each other, and the engine can push spent gas out more easily. That helps the engine breathe, and an engine that breathes better generally makes more power and sounds meaner doing it.
Why Factories Use Manifolds
It is not that the engineers at the factory did not know about headers. Cast manifolds are inexpensive, durable, quiet and simple to package around steering, suspension and emissions hardware. For a daily driver that never sees the drag strip, that trade-off is reasonable. For an enthusiast who wants more from a Hemi, it leaves performance and sound on the table.
Shorty Headers vs Long Tube Headers
Headers come in two main styles. Shorty headers are close to the size of the factory manifold and bolt into the stock location, so they usually work with the factory mid-pipes and keep installation simpler. They are a good step up for owners who want improvement without changing much else.
Long tube headers run the primaries much further down before they merge. That longer path is what most builders associate with the biggest gains in midrange and top-end power on a V8. The trade-off is that long tubes typically require new mid-pipes or connection pipes, more installation time, and attention to emissions rules where you live. They also tend to change the exhaust note more noticeably, which many Hemi owners consider a bonus.
Long Tube Headers for the 5.7 Hemi: What to Know Before You Buy
The 5.7 Hemi has been used across a long run of Dodge, Chrysler and Ram vehicles, so fitment is the first thing to nail down. Headers built for a 2005-2008 Charger are not necessarily the same as those for a 2009-2024 Challenger or a 2009-and-newer Ram 1500. Always match the year range, engine and body style in the product title before you order, and contact our team if you are unsure.
Next, think about the full system. Long tubes change where the exhaust meets the rest of the plumbing, so plan your mid-pipes, catalytic converter situation and cat-back together. Many owners also schedule a tune, because a Hemi that is breathing differently usually benefits from updated calibration. Finally, check your local emissions laws. Some header and mid-pipe combinations are intended for off-road or competition use only, and it is your responsibility to know what is legal where you drive.
BBK Long Tube Headers for Challenger and Charger
BBK Performance is one of the best-known names in Mopar headers, and we carry their long tubes in multiple finishes. For 2009-2024 Challenger and Charger 5.7 Hemi cars, look at the BBK 1-3/4 Long Tube Exhaust Headers in Titanium Ceramic or the Polished Silver Ceramic version. Earlier LX cars have their own option: the BBK 05-08 5.7 Hemi long tubes in Titanium Ceramic and the Polished Silver Ceramic version.
If you are running a 6.1, 6.2 or 6.4 SRT engine instead, BBK also offers the 1-7/8 long tube headers for SRT8 6.1, 6.2 and 6.4L.
Long Tube Headers for the Ram 1500 5.7 Hemi
Truck owners have not been left out. The Ram 1500 5.7 Hemi can get the same breathing benefits, and many owners pair long tubes with a cat-back to give the truck a deeper tone. We carry the BBK Ram 1500 5.7L Hemi Long Tube Headers in Titanium Ceramic and the Polished Silver Ceramic version.
Shorty Header Options
If you want a header upgrade with a simpler installation, shorty headers are worth a look. For 2009-2024 Challenger and Charger 5.7 cars, see the BBK 1-3/4 shorty headers in Titanium Ceramic. Earlier Charger and 300C owners can choose the 05-08 5.7 Hemi shorty headers. Ram 1500 owners have the 09-18 Ram 1500 5.7 Hemi shorty headers.
Don't Forget the Gaskets
Headers are only as good as their seal. A leaking header gasket causes ticking noises, lost performance and sometimes sensor problems. If you are pulling the factory manifolds, it is smart to install new gaskets at the same time. We stock the BBK Hemi exhaust header gasket set for Dodge cars and the BBK gasket set for Ram 1500 trucks.
Finishing the System: Cat-Back Exhaust for the Hemi
Headers handle the front of the exhaust, while a cat-back or axle-back system shapes most of the sound you hear from the driver's seat. Pairing the two is how many owners get the look and sound they are after. For Challenger owners, Corsa's Xtreme cat-back for the 2017-2023 Challenger 5.7L is a popular choice. Borla fans can look at the ATAK system for the 2015-2016 Challenger R/T or the S-Type catback for the 2011-2014 Charger R/T and 300C. Ram 1500 owners can check the Borla Touring cat-back for the 2009-2017 Ram 1500 5.7L.

Is a Header Upgrade Right for You?
If you drive your Hemi mostly on the highway and like it quiet, shorty headers or a cat-back alone might be enough. If you want the strongest pull and the most aggressive sound, long tube headers are usually where serious Hemi builds end up. Either way, a header upgrade is one of the most satisfying changes you can make because you feel it and hear it every time you drive.

Frequently Asked Questions
What is the difference between an exhaust manifold and headers?
An exhaust manifold is typically a single heavy casting with short passages that merge quickly. Headers use separate tubes for each cylinder that merge in a collector, which helps the engine move exhaust out more efficiently.
Are long tube headers better than shorty headers on a 5.7 Hemi?
Long tubes are generally chosen for the biggest power and sound change, while shorty headers are easier to install and usually keep more factory parts. The right choice depends on your goals, budget and local emissions rules.
Do I need a tune after installing headers?
Many owners tune after installing long tube headers so the engine calibration matches the new airflow. Check the product details and talk with your tuner about your specific setup.
Are long tube headers street legal?
That depends on the product, your mid-pipe setup and where you live. Some setups are for off-road or competition use only, so check your local laws before installing.
Should I replace header gaskets when installing headers?
Yes. New gaskets help prevent leaks and ticking, and they are inexpensive insurance during an install.
