What are the best headers for your WRX or STI?

Our Question of the Week this week is, what is the best header for your Subaru? Through all of the years that Subaru made the WRX and STI, they have used both equal-length and unequal-length headers/exhaust manifolds. Since the headers sit between the engine and the turbo, they play a large roll in how a turbo will spool up (especially on the EJ series turbo engines), what your peak power will be, and what your overall power curve looks like. For this reason, there is a lot of discussion about which style of header is best. There are some benefits to both the equal-length and unequal-length headers, and there are people that prefer one or the other. Generally speaking an equal-length header will be a more efficient design, but the unequal-length header is a big part of why Subaru's have a distinct sounding exhaust. But there are other things to consider as well. The size and type of tubing used are something to consider, as well as the overall design of the header. We take a look at those options and talk about where each of these options might be best. Thanks for watching and Stay Tuned!
