Hmm how did you gut them around inspection?? wont the sensors tell the story?? cutout perhaps??....
I have done some exhaust cuts in the past, and the gain is highly dependent on your current exhaust. I have seen a consistent .2+ second shave, and as little as a 0 second shave... *the .2+ second shave was on a 7.5L 455 with a sound suppressor and a muffler.
