Just wanted to know where exactly the part number is located at. I got a GMPP manifold from a member but I can't find the part #. Some numbers are on the part, none match the GMPP manifold part #. A Little worried its just a new stock manifold. I sure hope not. Anyone have some pics of there GMPP manifold?

Yea, thanks but that doesnt tell me where the number is engraved/shown on the part itself. Ohh well, it does look like that but I guess I'll find out when I do the install this week. Thanks again.

 

you could also just look inside the inlets and outlet to see if it looks smoother. See if there is a seam or anything like that, take some pictures and post em up so that other people who have handled one can chime in (i personally havent seen one in person though)

 

The number stamped on the GMPP manifold is the same as the one stamped on the stock one.

The only way you can tell a difference is once you pull the old one off and compare them.
