Doug Thorley headers
These headers are awesome. Definitely not the thin lightweight bargain basement pieces that will melt your plug wires and be rotted out in a few years. The flanges are very heavy and they use OEM type donuts with steel inserts at the collectors. Definitely well worth the extra cost and by far the best price was here at Auto Anything
99 k3500 4wd dually
The parts i recieved looked correct however they were not, they were for a 2wd truck not a 4wd truck. To make things worse this was not apparent until after i had cut old exhaust off and was trying to put the new exhaust on. This was my daily driver truck s o clouldn't wait another 3 weeks to get the right parts, so i had to pay a shop to put exhaust on the truck for me. Complete waste of money.
