Here it is, finally a fully fabricated high flow rear exhaust manifold to replace our discontinued Ported Rear Manifold! It is fully stainless steel and will outlast the car. It bolts in place of the stock rear manifold. It comes with new bolts and nuts for both connections.

It will work perfectly with our front Power Log. It will not perform as well as our full length Stainless Headers, but it sure takes a lot less time to install.

Pairs perfectly with our rear stainless power log and our stainless crossover. 

For turbo 3800 cars:
Since the Z3 and CarTuning turbo kits require the OEM rear manifold for the wastegate perch, this will work with both of those turbo kits. However, if you are running our Z7 or Stattama turbo kit, you would run the Turbo Rear Power Log instead. Those turbo kits have the wastegate perch on the crossover pipe.

Since this manifold doesn't have the recessed ring in the flange like the stock manifold does, we recommend using a 2 bolt 3" flat gasket instead.

Only fits W-Body.

Fits Lacrosse, but in 08-09 the crossover was different, so you would need to run an older style crossover. Will not fit Lucerne.
