Flat Flange Exhaust Hardware Kit Downpipe to Cat-Back

This set of replacement hardware is just what you need to join a standard 3″ flat flange aftermarket downpipe (like Invidia, VSC Performance, or many others) to most aftermarket cat-back systems. You can also use this hardware for any other standard 3″ flat flange exhaust joint.

If your cat-back and/or downpipe uses a donut gasket connection, we recommend this spring bolt set instead. 

Set of two metric zinc-plated plate nuts and bolts, plus (optionally) 3″ two-hole gasket.
