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, reusing all factory hardware and the o2 sensor.

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.

Includes:

• Power Log
• 2 grade 10.9 bolts
• 2 grade 10.9 nuts
• 4 heavy duty washers 

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.

Will not properly fit the H-Body Bonnevilles/Park Ave/Rivieras because the outlet is centered and the H-Body is offset.

Only fits W-Body.
