I had posted a couple of weeks back about failure in my Bassani headers. The tube that hooks up to the EGR fell out with the weld failing. Well the flanges were warped too, so I decided to replace with JBA, which I thought might be built a little better being stainless.
So now I have a fitment issue. with the JBA headers! The passenger side collector does not drop enough to connect to the y pipe, which is a Bassani. If I try to bolt it up, the y pipe gets into the oil pan long before the flange will seal up. I measured from the top of the header flange to the bottom of the collector bevel and the Bassani's I took off have one inch more drop than the same measurement on the JBA's, hence the problem. Although the part numbers match, 1628S, I thought that jBA made an error in boxing these up. Summit sent me a new set today, and they measure the same.
This makes no sense. I have never had a set of headers that would not bolt properly to this y pipe, and the difference in measurement between the Bassani and JBA headers is one inch, that accounts for the problem I see. What is going on??? Could JBA be making an error in building these? The Bassani Y pipe is not built specifically for Bassani headers, it should fit any header I would think.
