Default Re: Chambered Exhaust for 1969 Camaro

I have reason to believe the system changed slightly after January, the change noted in the assembly manual has to do with the 2 chambered pipes which run parallel to and aft of the rear axle. The original schematic (illustrated under L34-35 section in AIM) shows each chambered section with 2 tabs welded on them and then the tabs bolted together.

The NC8 section in the AIM shows the elimination of the nut, bolt, and lock washer.

It would allow the two sides to move independently of one another, which IMHO is not at all detrimental.

Has this change been noted on any actual production vehicles?
