Called gibson and they are coming out with a different exhaust system for the newer 3.7 (07's) and the it has a 3-6 week time frame. They said they had to make some changes to it because of the different engine. How much change could there be? No part # yet but is coming. So I will be waiting for that.
If anyone else would like to check back with them there # is 1800-528-3044

 

Interesting..the 07's may have a slight change in the actual piping or hanger locations..that would be a big change for the 06 exhaust systems to try and fit..

 

Hard to believe they would change the cat back after 1 year[&:]

 

3.5 to 3.7 big enough diff ?

 

Obviuosly there is some significant difference between the 07 and 06 exhaust system.

 

Hmmmmm.....interesting, installed a Magnaflow system (2006)on my 2007 a couple of months ago without any issues.

 

Hmmmm...well then maybe the 2006 Gibson should fit as well..thanks for the info tphnet

 

It may fit but maybe the changes are for performance reasons?

 

Any word on if Gibson came out with an 07 unit yet?

 

I just had mine installed on Wednesday and when the shop ordered it they said it was for the '07 H3 - I didn't get a part # off of the box though.....not sure if this helps at all.
