I have a 2009 Pontiac G6 GT coupe. It has the 3.5l engine with the 6 speed automatic transmission. It is fully loaded except it has cloth seats that are not heated or power. It is white and it has some 18" Velocity Rims with Z rated directional tires.  It has 120k and we are the 3rd owner. I am looking for performance headers for this car. If I have to manufacture them I will but prefer to buy some good mandrel bent ones 2 1/2" diameter. In a stainless or chrome finish. 

These G6s are fantastic cars. Have owned mine since new in ‘06. Only negative is there is not as much in way of aftermarket support compared to others, like a Camaro. Haven’t searched for headers in quite some time though so there might be something I’m unaware of. Otherwise may need to get a custom set done.

In other news, have any pics of the G6? We love pics here!  

I am not aware of anyone making a header for the G6 or the 3.5L engine. Custom made is the only way to go that I know of. If you go that route, be prepared to get a custom tune on your ECM too to take full advantage of your new headers.
