No "Stock" baseline... but here's the comparison going from the cat-back, to the headers, to the tune:

2011 LS3 w K&N, Magnaflow Comp Cat Back:
395.26 rwhp
383.38 torque

W/ SW 1 7/8" LT Headers NO tune:
415.7 -r

Completed, WITH tune:
427.99 -RWHP
416.15 -TORQUE
Not too shabby, especially at 95 degrees and 90% humidity!

Need to come up with another 22 HP and I'll be happy!
