Headers have a 1-5/8 tube with 3 inch collectors. I had to cut one tube and move it to get them to work with my angle plug heads. Hard to tell it was cut once they are installed. Got a few dings from suspention I guess nothing very bad. I also cut off the evac tubes and welded up the holes so there is kind of an ugly spot on the collectors. They function fine no leaks. I also have some 2.5 inch pipe to go with them bent for 3rd gen. Pipe stops at rear of doors I think. It is about 5 feet long. Sorry no pics. I will take 125.00 for the headers and the pipe or 100.00 for just the headers plus shipping. E-mail me with any replies. Thanks alot Gary
