Okay here goes,
I just received my new Magnaflow exhaust Kit#16884 for the 85 GN. I unpacked it all and went through all the parts I hoisted my car up and it looks as if the previous owner had put in a quick fix from a shop. The pipe does jot have the correct flanges on either end, the side closest to the front has a 2 bolt flange bolted in on an angle to somewhat work on a 4 bolt flange which is 3.25" square. As you see in the picture, the new y-pipe in the kit looks to be a 3 inch with a 4 bolt flange.
My question is where can I get the "test pipe" that goes between the 2 sides. I am sure the 86 - 87 had cats there, correct?
I will post a picture of the kit, the flange end on the y pipe, and also have picture of the part that I need circled in red in one of the pictures. Hooker sells an exhaust kit for the buick turbo cars that has the test pipe in the kit. Also I will post a picture of the mickey mouse pipe that is under my car as well.
If anyone has a spare pipe kicking around please let me know, or knows where to get one, Pypes, Walker Etc.
Thank you.
