Yet another stg2 sti dyno plot........
Except that its MINE!
I finally ditched the stock catback exhaust for a Borla Hush twin tip.
I had to make a few small changes to the Borla. The biggest was getting rid of the stock 2.5" donut gasket/flange and replacing it with a 3" Vband. I also did a few small changes to the position when the V-band was welded in.
The end result is a true 3" turbo back exhaust that turned out to be just slightly louder than stock. Just enough to hear the rumble below 3K rpms and putting around town.
I also installed a new OEM flywheel and ACT clutch, along with new trans fluid, and engine oil change. 74K on the ODO.
Here is the best run from last year, after I moved to Texas (run file 007) VS today's final tuned pull (run file 021)
Note, I was on stock clutch & stock catback on runfile 007.
Here is just the new clutch, borla catback vs stock catback, stock clutch:
Here is the results just from tuning today:
And finally here is my final tuned pull against a stock 2012 sti:
