Subaru headers are a little different than most automotive headers. Subaru headers do the same thing--facilitate efficient evacuation of exhaust gasses. But since Subaru uses a horizontally-opposed engine design, Subaru headers have two (or three, depending on which model you have) pipes on opposite sides of the engine from each other. There's nothing wrong with this design; we're just letting you know what to expect when you open the box for your Subaru headers. Like all exhaust headers, Subaru headers are one of the fundamental upgrades that have to be made to help your engine breathe freely. Subaru headers are particularly important on turbocharged vehicles, where the exhaust pulses drive the turbo on their way out back. We have premium-quality Subaru WRX headers, including the Subaru STI header, available from many different manufacturers, so you can choose the best Subaru headers for your vehicle and your checking account. One thing all our Subaru headers have in common is that they come with our guaranteed low prices and impeccable customer service. We keep all our Subaru headers in stock and ready to send out, and we'll ship your Subaru headers the same day you order them. It's differences like this that make us the leading retailer of Subaru headers on the web.
