well, I finally got to take the car our with the new 2" headers. what i can tell is it is definitely louder than the 1 7/8". I'm noticing a little more pinging noise from them. Don't know if they are made with the same thickness of metal or not. After everything settled its still hitting the damn frame on the passenger side. I might leave it because it's such a pain in the ass to remove. ill most likely address it over the winter. For the price it's definitely worth the price and time to install, even if you have to dimple 2 pipes.
