Still waiting on the mating headers on back order, need to see how well they mate up.. Instructions would be nice as I went to install the glass pack type mufflers and and they only went in a couple inches, do I pound them in, concern is the ceramic coating cracks.... Has anyone done this? Hello me out please. Thank you

Good product, this is my second set. I remove the fiber wrapping from the mufflers. It burns up quickly anyway. The mufflers still keep the noise level down. The coating on the pipes is pretty good and you can polish it.

Good quality and construction, would recommend.
