I'll add some more info to this later if you're interested to see my other big project car.
2009 CTS V sedan (556hp stock)
6spd 6L90 auto (the next step above the C7 auto trans) - built/upgraded by Circle D
3600 stall triple disc torq converter - Circle D
Built 388 4.125 bore LSA motor - sleeved by ERL, built by Bischoff
RaceTech copper coated pistons
Lunati I beam Rods
Callies Magnum Crank
Brodix BR7 heads with our port flowing 415cfm at cam lift
Cam - custom grind .655 lift
Squash dual return system for e85, flex fuel sensor
ID2000 injectors
Procharger F1X with 2 race valves (one wouldn't cut it)
Stainless works custom headers, 3" magnaflow mufflers for street, 3.5" Borla XR1s for track
yadda yadda yadda
this is the 3.5" exhaust if I recall - a little rumble
the sound is intoxicating, esp when driving it
