Long tube headers vs. short tube headers

Long tube headers are better for high-RPM performance, making them ideal for track cars and performance builds. They reduce back pressure, improve exhaust scavenging, and increase horsepower at higher engine speeds. However, they can be difficult to install and may increase turbo lag in forced induction setups.

Shorty headers are better for low-to-mid RPM torque, making them a great choice for daily drivers and turbocharged applications. They are easier to install, provide better clearance around the engine bay, and improve throttle response in the lower rev range.

If you want maximum high-end power, go with long tube headers. If you need better drivability, quicker turbo spool, or easier installation, shorty headers are the better option.

Frequently asked questions
What are the benefits of installing long tube headers on a 2004-2013 Chevy or GMC 4.8L, 5.3L, or 6.0L engine?
Installing long tube headers with a Y pipe improves exhaust flow by reducing backpressure, leading to increased horsepower, better torque, and improved throttle response. These upgrades also enhance fuel efficiency and give your Chevy Silverado or GMC Sierra a deeper, more aggressive exhaust note.
Are long tube headers better than shorty headers for my Chevy or GMC truck?
Yes, long tube headers provide superior performance compared to shorty headers, especially in high-RPM horsepower gains. If you're looking for the best upgrade for towing, off-roading, or high-performance applications, long tube headers with a Y pipe are the ideal choice for your 2004-2013 Chevy 4.8L, 5.3L, or 6.0L engine.
How much horsepower can I gain from long tube headers with a Y pipe?
Installing long tube headers and a Y pipe on a 5.3L Silverado or Sierra can add 15-30 horsepower, depending on the tune, supporting mods, and exhaust setup. When combined with a performance intake and proper tuning, you can see even greater gains.
Will long tube headers change the exhaust sound of my Chevy 5.3L or 6.0L engine?
Yes, long tube headers with a Y pipe will deepen and amplify your truck’s exhaust tone, giving it a more aggressive, race-inspired sound. Pairing headers with a high-flow performance muffler will further enhance the exhaust note.
