Emissions

This part is legal for sale or use on Emissions Controlled Vehicles, Uncontrolled (Non-Emissions Controlled) Vehicles, and Racing Use Only Vehicles because it does not affect vehicle emissions and is not covered by emissions regulations.

See Emissions Details
When installing headers you will need header bolts, factory exhaust manifold bolts won't work. These Mr. Gasket Header Bolts are Grade 5 for strength, black oxide coated, and have a hex head that is ideal for use where space is minimal - your typical header flanges. Ever had a set of headers where a socket just seemed it wouldn't fit? These bolts also have a socket head or Allen key drive in the center for just that problem.

Sold as a set of 12
