  • Product fit well and with a little effort matched up with the existing exhaust manifold and tailpipe. A small amount of grinding was need to mate it up with the tailpipe for a perfect fit. Otherwise went together easily.

Customer Review: (see review/s)
  • I'm very pleased with this product. It bolted on easily and the dimensions were perfect. But like I said before the top didn't sit perfectly into the exhaust manifold. But it is well made and I passed emitions. And a big plus, it costs hundreds less than an original part. And I have more horse power in my truck now. Thanks.
