Hi have a 2013 gs f sport AWD was looking into installing a joe z exhaust system, currently only the axle back fits but was wondering if there was anyway for the cat back to be installed. The sound of the cat back just sounds much more aggressive.

 

Not possible. As far as I know they have no plans on making a cat back for AWD.

 

What is it that stops them from not being able to have it installed if you know by chance?

 

The axle is in the way, you need to run the pipes around it. JoeZ has to create a new design specially for AWD. We've asked but I don't think they are very interested.
