Appears to be a little thicker than original. Exact fit, a lot less money than,original. Only negative was exhaust flange gasket didn't center it's self into the manifold well. I didn't want possible leak,so i cleaned original seal and used copper coat spray to reinstall.

From Boston
I had a leak in my manifold area so I decided to replace the whole shebang since this product was relatively cheap. The manifold itself seemed to be good quality and fit well. The only issue is that there is an additional hole in it that is not in the OEM manifold, which is only covered by a metal plate and gasket. The metal plate is attached in a wat that it's levered AWAY from the hole its covering. You can see it in the product image. The gasket itself blew out on my first test drive after installing! I had to plug it with exhaust cement, so we'll see how long that lasts. Also the bolts included were useless. I had to buy additional bolts for the manifold to head as well as the manifold to the lower exhaust.
Bottom Line not recommended
