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.

3. Remove the spark plugs.
