Rennkraft Sport Cat and Competition Link Pipe
A patented Fabspeed's patented modular design that lets you swap between a catalytic converter and a straight-through bypass pipe on the same mount. link pipe for the Porsche 964 and 965 Turbo (1990-1994), replacing the restrictive factory catalytic converter with either an HJS 200-cell catalytic converter or a straight-through bypass pipe on the same mount, so the car can run catted for daily use and switch to the bypass for track days. It keeps the stock OEM rear mufflers so the car still looks original. Built from 3.0-inch, 14-16 gauge CNC mandrel-bent T304L stainless steel and bolts directly to the stock DLZ or K27 turbo. Expect a noticeable jump in volume, pops and gurgles, and turbo whistle with the sport cat; the bypass pipe is louder again, with pronounced turbo spool sound in the cabin.

What's the difference between the sport cat and cat bypass configurations?
