Kits with Hedman's HTC polished silver ceramic-coated, or Black-Maxx satin black ceramic-coated headers are also available.
Headers are backed by a limited lifetime warranty. All other components are covered for a full year from the date of purchase.
**The transmission crossmember in this kit is designed for use on cars with a factory THM200R4 frame rail extension on the driver's side. For vehicles that do not have this extension, the use of a Trans-Dapt #6423 frame rail adapter kit is required (sold separately).
