I'm pretty warranty sensitive too, which is a big reason I'll be sticking with the SPT exhaust for stage 2.
It's a decent return for the cost of an AP. Protunes at Surgeline are half-off if you buy the AP at the facility.
Thanks I appreciate the response. I "had" a 2004 WRX a few years back. I had a COBB version two AP. But I did and up pipe, down pipe, with Turbo XS all at once. Woke up the car BIG TIME!
I wanted to verify that on a stock STI that a Stage one flash was "felt" and or worth it.
