Did you ever make any progress with this? I just ordered a Kicker Mono amp 400.1 and 10" Downfire CVT Sub enclosure. I spoke to kicker and they said it appears to be the same sub in the gm accessory kit but the one I ordered has more range and volume. I'll try to update after install.
I'm with you on this! Interested to find out the answer.
I'm not 100% sure on our trucks but almost all stock exhaust is stainless steel now a days. No need to replace the piping in my application.
Do you have a part#
Has anyone installed these on a 2wd truck? Iv searched and read as much as I can and everything seems to go back to 4x4 trucks.
I want to put these or the Eibach on my 2wd 19' Elevation.
Thanks for any feedback in regards to the 2wd or Bilstein vs Eibach.
Thank you
