Default Borla catback has actual power gain

There's nice tunel in Korea to test whether the mod is effective or not.
In the tuner, even I can reach to the limit(283km/h) and keep that speed for a while.
I ran with full exhaust mod car when I was almost stock
His car has sikky headers, custom catback exhaust, 200 cell race cats and limmit cancle kit.
At that time, he pushed forward from the beginning. We usually start rollin from 60km/h, and the distance between his car and mine was at least 60 meter when I reach 230km/h.
At that time, my mod was just lems titanium intake pipe and blitz drop in filter.

This time, my car was added borla catback only. I installed the exhaust about 2 month ago. And I ran the same car several times yesterday which has no change sine then ( headers, catback,, high flow cats, littmit cancle kit).
And then I got something an incredible result ..

He could not run over me until 230km/h when I had just little early start.

And when we started even(simultanously), He left me behind about 10 meters when I reached 220km/h ( before installing borla the distance was about 60 meters )

Honestly, until yesterday, I just had a 'feeling' that my F got some power after borla catback installed. I thought the effectiveness of aftermarket exhaust on N/A car was just for sound itself ( I'm not talking headers )
But, It's pretty ovious that proper aftermarket catback exhaust has power gain.

I have some vid on each result.
I can not upload the vids for my personal reasons
Anyone wants the vid, quote your email address.


Oh by the way
What's your data about c63 amg?
He can beat 09~11 c63 ecu tuned 525hp mod, even 12~ stock c63 mct version
