No worries - I actually just completed it last week :-)
We had a lift adn the tools, so it made it much easier than I expected. I have headers and hi-flow cats on it now, when I get back in town I'll be taking it to get the rest of the 3" exhaust bent (not gonna try that).
Hi - I'm purchasing the Texas Speed 2" headers for my 2015 SS M6. I'm curious, I see you didn't have install issues, are you still happy with the setup? Also, what did you do for the rest of the exhaust? Did you buy the kit that had cats, buy aftermarket cats, or go cat delete? Just looking for the best options and cautions.
