This is a new stock K04 KO4 exhaust manifold with heat shield. It is off a LDK/LHU (Regal/Opel) engine so it is not a direct perfect bolt in replacement of the stock Cobalt or HHR manifold, however it will function perfectly fine. There are just a couple differences in where the bracket and heat shield bolts up.

• 11+ Buick Regal 2.0L Turbo
• 2008-2010 Chevrolet Cobalt SS
• 2008-2010 Chevrolet HHR SS
• 2011 Saab 9-5

Will physically bolt up on a Saturn Sky/Pontaic Solstice with the 2.0 LNF, however due to the offset on this manifold your turbo may hit your frame rail.
