Exhaust Header VS Manifold, which is the better choice?

When it comes to improving engine performance, Sentra headers offer a clear advantage over traditional exhaust manifolds. The key differences lie in their design, material, and flow efficiency. Headers are made from lightweight stainless steel and feature individual tubes for each cylinder, helping to eliminate back pressure. In contrast, cast iron manifolds are heavier, shorter, and more restrictive — often reducing airflow and horsepower.

By allowing exhaust gases to exit more freely, headers unlock extra power and a more aggressive engine sound. This makes them a popular upgrade for drivers looking to boost performance both on the street and at the track.

FLASHARK’s direct-fit exhaust headers are engineered for easy installation — no cutting or welding required. Whether you're upgrading for power, sound, or style, our headers are a bolt-on solution built for your build.

So far impressed

Was hesitant with how low the price was, but was pleasantly surprised with the fit and finish along with the pretty decent weld work and no interference with surrounding parts (alternator clearance was my concern due to seeing other branded headers having an issue with that area). I also did have to ever so slightly die grind the outer most holes to clear the studs by 1-2mm on each outer edge, but there was plenty of meat on the flange to not compromise the install/seal. Came with a new gasket and 4 studs/nuts which I didn't need, but also worth noting that 5 are required not 4...no biggie but fyi. I advise making sure the header is cleaned/degreased before starting engine and allowing the metal of the header to get to engine temp other wise hand marks etc will show where oils burn in. Sound wise, it did add a nice grunt to exhaust tone paired with OEM midpipe and Nismo catback exhaust. Wish there was a midpipe available to complete my exhaust. So far no issues, and hopefully lasts a while

Can you provide the year, make and engine model of your vehicle? Thank you for your review and suggestions, we will continue to improve!

Good product

No issues with install. Was afraid there would be a clearance issue but everything lined up. Got rid of CEL which was initial reason for swap (my engine type is notorious for precat issues which could lead to engine failure if left unchecked), overall very happy with purchase would buy again.
