PERRIN STI Equal Length Header

Updated from July 2010 post with new pics and new data! When Subaru released the Version 8 STI in Japan we noticed how they moved to a twin scroll turbo and equal length exhaust manifold. This is what inspired us to make our first header for the WRX/STI! Would taking the equal length design of this JDM header and adapting it to fit our US cars actually make a difference in power? Would it spool worse?  How would the sound [...Continue Reading...]

PERRIN EJ Series Upgraded Engine Mounts

This has been a long time in development and a long time in testing, and its finally ready to sell! We spent many months testing this part in-house and many months testing this in customers hands, to ensure this part will hold up to any kind of abuse our customers can give it. The idea of this part is simple. Stiffen up the engine to reduce the entire drivetrain movement under hard acceleration deceleration and corning, to effectively transmit more power [...Continue Reading...]

BRZ/FR-S Part Proving.... All Bolt-Ons Part 2  (Header Tests)

…..Continued from BRZ/FR-S Part Proving…. All Bolt-Ons Part 1 This was the first time we had tested our headers on the dyno. Based on the things we know about the car and some of its variables, we knew it would be key to do this all on the same day as all the other parts. This ensures that the HP gains we saw were legit. After seeing some peoples dyno results showing huge gains of 15-20 WHP I was excited [...Continue Reading...]

How-To Load Custom Maps Onto Your AccessPORT

How-To Datalog Using Your AccessPORT (Subaru)

From time to time we may ask our customers to provide us with a Datalog to help diagnose a problem or help make their tune a little better.  So what is a Datalog?  A data log is just that, a log of data!  The type of data being logged is parameters and information your ECU is using to control your engine. These are things like Engine RPM, Boost, Ignition Timing, Engine Load, and Air Fuel Ratio, all of which are [...Continue Reading...]

BigTube Equal Length Header

A new part brought to you by….. you!   Over the last few years our Equal Length Header 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 [...Continue Reading...]

Video Promo - PERRIN Stealth 2011 STI

Perrin Performance Promo from J. Christopher Miller on Vimeo.   A good friend of mine Chris Miller called me a few weekends back and said he had an opportunity to play with a really cool Sony F3 35mm HD video camera. This is one of those $20,000 cameras used in the film industry to make full length featured movies and commercials and what not.  He wanted to come by and shoot my STI (recently matte blacked) to do some testing [...Continue Reading...]

Customer Tune - Thomas Powers

Thomas begged me for about a year to tune his car and I finally gave in a few weeks back, when I had some spare time. Thomas’s 07 WRX, as far as drivetrain and engine parts, is a typical Stage 3 car with a TMIC, but it has a gearbox with the JDM RA gear set installed. The gearing of RA gear sets makes it really fun to drive, lost of shifting, but super close ratios.  For sure a good [...Continue Reading...]
