MUST be used with our RoadsterSport Midpipe or Magnaflow System One, will not install to small inlet of factory midpipe or other Magnaflow systems.

So, you can work from the back of the car if you want to buy one piece at a time but that means you start with our DUAL or QUAD muffler, then get the Midpipe for a little sound and better flow, and then finish off the system with this Crosspipe.

Give your turbo a full 2.5 inches of flow all the way and it will make you smile like never before! Automatic transmission compatible crosspipe has 2.25" piping to clear the transmission.

Yes, this is a CARB legal 'cat-back' item because it bolts to rear of stock converter.

This is the path to 200 Ft/lbs of Torque per our dyno graphs in our forum Fiat thread! All POLISHED stainless steel construction and LIFETIME warranty. See our forum pictures showing comparison of restrictive stock crosspipe that crushes down to under 2 inches of flow, versus our clean 2.5 inch diameter highflow replacement.
