Perrin equal length headers are designed with performance in mind. Each kit is specifically made to maximize the horsepower of your Subaru WRX. These top-quality headers are made of solid 304 stainless steel and brushed to a fine finish. The thick flanges provide a smooth surface to mate to the head or turbo, preventing exhaust leaks. The headers do not require tuning to be used and can simply be installed and driven immediately. Perfect for adding power, lowering spool times, and getting a more refined note from your exhaust.
