Had a little fun with an LS2 GTO today. He was modded, but I am not sure to what extent, but I could tell he had a catback.... It was pretty loud though, so I assuming the basic GTO mods like header, intake, catback.
There is not much to tell here except that I got fcking owned! And when I say owned, I mean he pulled bus-lengths on me
I knew the LS2 GTO was fast with bolt on's, but I didn't know that fast. After some brief research, I am finding out that exhaust mods alone will put them into mid-low 12's @ 112mph or so... And with a tune/flash low 12's @ 115mph are to be expected.
