The picture below i




s a CTS-V on the left and a SS Trailblazer on the right. The problem with this setup is the CTS has a huge 3" opening and a bolt pattern that 4-5/8 center to center on the studs and the TBSS Manifold is 2.5 so I have some fabbing to do on it.

The balancer is 1and 3/4 inch above the original crossmember.
