Well, I drove the GN this morning, and had the up pipe blow off at the top. Never have had a problem since the new 3" up pipe, but I guess the T bolt clamp wasn't quite tight enough. Anyways, it tore up the hood insulator pretty bad. Anybody have any cool ideas for a new insulator? I may go back stock, but really don't want to pay $400 to try to find an NOS liner.
