Thank you. You have rated this product.
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.
MUST be used with our RoadsterSport Midpipe, will not install to small inlet of factory midpipe. 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.
Install Notes: Note that bracket attached to stock mounting point and the stock mounting point has room for adjustment as needed if you follow it back upward. Connection at midpipe needs to be done with patience, start with studs and then add the springs and then add the retaining nuts. If nuts are jammed onto the stock studs before you start you need to separate those nuts with 13mm wrench, trying to force the studs over the springs and get the threading started with nuts already jammed onto the studs is too hard to do.
