Great Price 67-76 Mopar A-Body Complete Stainless X Pipe System Hooker Blackheart 2.5" & 3" - Under $400 & Free Shipping
I just purchased the 3" kit for my 68 Dart after seeing this thread. Kit came within 2 days of ordering it and looks pretty good. The 3" system actually does have the X pipe shown in their photos, but will require a little work as there is still only a small hole going between the two tubes. It will still be a few weeks before the car is ready to install the exhaust, but I am hoping it fits well. From looking at the kit is looks to be a great value for what you get.
