Preforms as should!

Package arrived with manifold loose in box (no packaging material). Was in a plastic bag in the box. In the bag there was a lot of metal shavings and flakes. I measured the ports and all of witch where larger than the stock manifold. There was a spot I had to take a bur off in one port. I have installed manifold on a 98.5 Dodge 2500 with 4 inch silverline exhaust and a edge tuner set at light trailer tune for the best fuel economy as the only other mods. Install time with removal of old exhaust manifold was about an hour (turbo removal not necessary). It preform well. Exhaust gas temperatures have lowered, there is a better throttle response and a slight bit of more turbo whistle. No increase in MPG's. FYI the only gasket you need to get is the turbo to the manifold gasket the 6 manifold to head gaskets are included. I like the product but it should of been package better and the ports could of been cleaner for the price. Not blaming XDP. The manufacture needs to a little better on there end.
Good Product But.

My overall impressions of this product was wow. Its built much better than OEM and should given its 3.5 expensive as oem. Installation was tough but I did not take off the turbo. Everything is given to you and I even got gaskets with it which is odd because they said that the kit did not come with gaskets. The manifold is not painted black as shown in the photo but has the stainless steel finish. On another not, they shipped it in a reasonable time given it was out of stock but the packaging was sub-par. The package was broken upon arrival and the exhaust manifold was exposed. Not a good sign.
