Just wondering if the exhaust system for the 4.4 2009 STS-V will bolt up to the 4.6 manifolds? They look the same, but not positive

Cause I was rear ended a couple weeks ago, bent the exhaust and the factory system is $1866 from GM. And Borla has a full system for $1500.

----------

Want to upgrade and can't find a complete exhaust system for 4.6 Northstar

Really!! I'm just waiting to see if the insurance company of the lady that hit me will give me a check for the exhaust part of the claim, then I will be on the hunt. I will keep in touch

Checked with dealer today, they show a performance exhaust system, but it is not available anywhere in the U. S.

Order directly from Borla ... I did it about a year ago now. I have the GMPP exhaust.
