Join your HEMI headers to a 3-inch rear exhaust
Build the exhaust around your naturally aspirated HEMI with Kooks Performance-catted connections. 31023200 uses a 3-inch inlet and 3-inch Race outlet, linking the matching long tube headers to a suitable 3-inch aftermarket rear system.
SKU: 31023200
Choose for a naturally aspirated engine
These 304 stainless connections use Performance cats and are not recommended for forced induction. The confirmed offer covers the naturally aspirated 6.1 and 6.4-litre applications shown in the fitment table.
Match both ends of the connection
The front requires Kooks long tube headers. The full 3-inch rear outlet needs a matching aftermarket exhaust. If you are retaining an OEM-size rear system, choose the appropriate OEM-outlet connection product instead.

Frequently asked questions
Can I use these on a supercharged HEMI?
The Performance-catted 31023200 is for naturally aspirated use and is not recommended for forced induction.
Does Race refer to an uncatted pipe here?
This product has Performance cats. Race identifies its 3-inch rear connection, rather than an OEM-size outlet.
