Actually yes. I'm torn with this. I have a bad scr and they are on backorder. I want my vehicle to be more reliable and not have to pay so much to get this emissions components fixed throughout the life of the vehicle. I also care about air quality, water quality and climate change. I know there are worse offenders, that doesn't make contributing more acceptable.

That said, if the reduction in nox is minimal, I could live with it. The performance isn't as much a factor as reliability for me. I wish there were after market parts for this system.
