Exhaust, resonator swap?

  • 2006 PONTIAC G6
  • 3.9L
  • 6 CYL
  • 2WD

Can a resonator for a Pontiac 2006 GT fit a Pontiac 2006 GTP? I tried and tried and can't find one for the 3.9 engine.
Do you
have the same problem?

I think you can here is the information the manual gives you, I have also found diagrams on how the exhaust system looks (below) and how to install it with bolt tightening specs.

Important: Use of non-OEM parts may cause drivability concerns.

The exhaust system carries exhaust gases, treated by the catalytic converter, through a resonator, if applicable and into the exhaust muffler where exhaust noise is lessened.

In order to secure the exhaust pipe to the exhaust manifold, a flange and seal-joint coupling is utilized. The exhaust system may utilize a slip-joint coupling design with a clamp and a U-bolt or a flange connection with a gasket.

Exhaust hangers and rubber insulators help to support the weight of the exhaust pipe along with insulating any exhaust system vibration, rattle, or noise.

Exhaust hangers also space the exhaust system away from the underbody of the vehicle and allow the exhaust system to expand as the exhaust system warms up.

Exhaust heat shields are used to protect the body and other components from damage due to the heat from the exhaust system.

The exhaust system may be comprised of the following components:
Exhaust manifold
Exhaust pipes
Catalytic converters
Exhaust muffler
Exhaust resonator, if equipped
Exhaust tail pipe, if equipped
Exhaust hangers
Exhaust heat shields

Some exhaust systems are equipped with a resonator. The resonator, located either before or after the muffler, allows the use of mufflers with less back pressure. Resonators are used when vehicle characteristics require specific exhaust tuning.

Catalytic Converter
The catalytic converter is an emission control device added to the engine exhaust system in order to reduce hydrocarbons (HC), carbon monoxide (CO), and oxides of nitrogen (NOx) pollutants from the exhaust gas.

The catalytic converter is comprised of a ceramic monolith substrate, supported in insulation and housed within a sheet metal shell. The substrate may be wash coated with 3 noble metals:
Platinum (Pt)
Palladium (Pd)
Rhodium (Rh)

The catalyst in the converter is not serviceable.

The exhaust muffler reduces the noise levels of the engine exhaust by the use of tuning tubes. The tuning tubes create channels inside the exhaust muffler that lower the sound levels created by the combustion of the engine.

Check out the diagrams (below). Please let us know if you need anything else to get the problem fixed.
