Just got some time to get some more uploaded onto the ol' computer & thought I would share the results with ya! All charts have a before & after...
2005 WRX STi with APS equal length headers, uppipe, turboback, stock VF39 & Perrin front mount.
2002 WRX Wagon with STI shortblock, turboback exhaust & stock intake.
And our latest...!!! This is a 2007 WRX. The low chart is a stock pull with only a turboback exhaust & APS 65mm cold air intake. The after is with a vf34, APS DR525 FMIC & COBB uppipe...all three were tuned with COBB's AP!
Check em out!
p.s, sorry Morgan, I forgot to post yours up!
