Sound

Expect a noticeably louder, more aggressive tone than the factory exhaust. The kit includes a resonated front pipe and rear muffler assemblies, but this is a performance system and it is not designed to sound like stock. Please check your local noise laws before installing.

Use and installation

• Sold for off-road / show use where local noise rules apply. It is the buyer's responsibility to make sure the use is legal where you drive.
• Professional installation is recommended.
