The RX-8, 3 inch, Super-Cat V2.3 replacement
cat pipe is here. This pipe replaces the factory cat-pipe
perfectly and is a true bolt in. Like the race pipe,
you get a noticeable improvement in power, and a throaty
exhaust note. The Super Cat-pipe is a completely new
catalytic converter design that allows extremely high
flow and still works with the factory OBD2 system (no
Check Engine Light!). Since the release of the original Super-Cat in 2004, this system
became the most popular catalytic converter replacement for the
Rx8 in North America. Why? Because it works!
