Many factors affect the installation of headers, some of which are broken or aftermarket motor mounts, accidents that impact
the configuration of the frame, and/or the installation of different engines or aftermarket cylinder heads. Most installations
require some welding. If you are uncomfortable with welding operations, we recommend that you contact a professional
exhaust system specialist to install your new headers.
Attention Customers breaking in new engines: Due to the extreme heat generated during the break-in process, the
appearance of the ceramic coating may be altered in certain areas. The protection characteristics and thermal barrier
properties of the coating is never compromised. It is recommended that a cast iron manifold or old set of headers be used for
this process.
Notice: The coating of these headers can be marred or scratched during installation. If the header needs to be returned and is
damaged, you will be charged for recoat.
