Hi,
For those of you who complied to the C6 w/ LS3 emission recall (where they change your cats), how does your car run? Is it any slower, are you sorry you did it or was it an improvement? Does the modification effect the NPP exhaust? Change the MPG?
I asked this last year and got mixed answers, I'm curious if you feel the same way. I never trusted the government when it came to emission controls and inspections, and my cars usually ran better when I did my own modifications. I have a base model 2008 w/6spd and NPP.
thanks for your comments.

You might post in the C6 general section. ZR's have an LS9.
