Well I tried for a long time to find the answer to no avail. Does anybody know of the differences between these Borla Atak catback exhausts?

Aside from the obvious that it's saying one is for a 2011-12 GT/Boss and one for a 2013-14 GT/Boss. It looks like one has an extra piece of small piping. Most vendors on here only sell one borla atak catback and list it as 2011-2014 fitment. A few places like Summit sell both. I was under the impression that exhausts were the exact same for all 2011-2014's. Since it's late, I couldn't call Borla. Thanks.

 

I'll double check, but my Borla cat back didn't have these small peices and fits fine.

 

I think the 140516 is a cat delete?

 

Hard to tell what they are from the images. Have you contacted Borla for an answer?

 

The difference is in he tip length size. 2013 and up has a rear diffuser that has the 2011-2012 style tip stick out. Hope this helps, let us know if we can help you out we have some 2013 and up cat-backs on order.

 

sure enough.. shorter tips..

 

Thanks Jay, I appreciate the help!
