This is my series four Mazda RX7 13B turbo when i took off the Exhaust just after the cat. The system consists
of a 3inch turbo back into an unknown
cat, with another 3inch pipe off that.

Mazda Rx7 4-rotor race car. The making of a Defined Autoworks Beast. [Offical Video]
Never before seen footage showing the assembly/start-up of our custom
4-rotor. It is the first 4-rotor since the 787b to use triple spark plugs
per rotor. It is also the first since the 787 to feature telescoping intake
manifold. Custom made slide throttle body system. A world first however is
the use of a center main bearing and 4-piece eccentric shaft. Quick specs-
9.7:1 rotors, lightened and race clearanced. Race main bearings, and race
rotor bearings, ceramic NRS 2mm apex seals. Custom stationary gears, Full
custom Peripheral Port in each rotor housing (defined auto), Aluminum side
housings for reduced weight. Needle roller bearing in the center housing.
