Our original replacement line is developed from the original sample. Our product is not the result of a copy of another manufacturer’s product. When developing from the OE sample one can insure the proper flanges, hangers , brackets, tubing diameter, etc is within factory specifications and not a ‘guess’ of what the factory item is. In additional, once the prototype has been developed, the item is test-fit and ran through a variety of tests to insure the product will perform as developed. What this means to the installer is an item that is guaranteed to fit right the first time, and eliminate comebacks. Not only is the fitment of the item tested and verified, the product is also tested on car and driven a certain amount of miles before it is released for production and sold to the client. Our direct-fit line means just that, no cutting or welding. A large number of items come with complimentary gaskets to ease the installation process. If gaskets are not available, our product is designed to accommodate the OE or factory gaskets without an issue. This makes sure you are not scrambling for gaskets to finish the install.wledge above all else. We provide the consumer with First-line products at 2nd line pricing. Dollar for dollar no-one else comes close
