Exhaust Header VS Manifold, which is the better choice?

Upgrading to Flashark exhaust headers for your 1997-2005 Subaru Impreza 2.5L or Legacy GT improves both performance and sound. Unlike the stock exhaust manifolds, which are made of thick iron and create back pressure, exhaust headers are made of lightweight stainless steel and feature individual tubes for each cylinder. This design helps to reduce back pressure, allowing the exhaust gases to flow more freely and increasing horsepower by up to 20 HP and torque.

In addition to performance gains, these headers give your vehicle a more aggressive exhaust sound. Installation is easy with the direct bolt-on design—no modifications needed.

If you’re driving a Subaru Impreza RS, Outback Sport, or Legacy GT, upgrading to FLASHARK Exhaust Headers will deliver noticeable improvements in both performance and exhaust note, all while being simple to install.
