Perrin BigTube Equal Length Header Subaru WRX 2002-2014 / STI 2004-2017


Perrin 02+ WRX / 04+ STi Equal Length Header 1.625 inch Primaries (Big Tube)


Over the last few years our Equal Length Header for the Subaru WRX and STI has been one of our most popular and most loved parts we have made. From the beginning we choose a perfect size tube for the primaries which produced more power and quicker turbo response compared to any other header out there. This was proven first by us, then by customers on forums and other shops.

Even though its been a huge success for us, we still had customers that asked us for a bigger header. They thought that our header was “Too Small” and would restrict HP. Even with our proof of the header increasing spool and HP on cars making 400+ WHP, customers still asked for a bigger diameter header.
