Rating: (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." posted by: on January 26, 2011 view all 2 reviews
