Maximum performance
I have recently installed ARH 1-7/8 headers with a 3" catted y-pipe to a 2.5 " Borla Atak exhaust . 2011 GS 6M, Haltech heat shield, MGW shifter. I've had it tuned and achieved 420 Hp and 400 lbs of torque. Is there any other "performance upgrades" I can do without opening up the engine (Heads, cam).
Ported intake? I do not race my car, It's my hobby.

Yeah fast or msd intake.. and depending on your definition of opening up the engine you could put 1.8 rockers on instead of the 1.7's
Would be like a very mild cam and give you more lift and duration at 0.050 by roughly 5.8% (1.8/1.7)
