"This company was fast in shipping very knowledgeable about the product and they also provided the gaskets and paid for return shipment. I had ordered these same items from another company they were not made correctly, came with no gaskets and I could not find any gaskets that fit even online they kept telling me I was wrong. When the mechanic put the converters to the manifold they were not even made correctly. Your company did an outstanding job made a 2 months waiting period for me turn into a two day process. Thanks for being so professional and patient. I will be back for more cars parts for sure. They even provide you a place to turn the items back in and get a refund." posted by: Candy on April 17, 2012
