These videos remind me of the potential of my car - I've got a stock C7.5 S6 - Humble and tame beast - It is nice to see and hear the potential of what I have sitting in the garage. One day I will tune, I have about 50K worth of Extended Warranty to get through first. Gawd that sounds nasty.
doesnt the 4.0T throw a CEL with DP’s, regardless if its hi-flow catted? i mean its why ive stayed away from doing them unless everyone’s CEL came from crossing the downstream o2 sensors
