I got an e-mail from Jon Bobroff with The Other Guys Performance Products, asking if there is enough interest within the G6 community to start R&D on headers for the G6.

According to Jon, The headers would be similar in design to the 3.4\3.8L headers which include the following:

14 gauge mild steel
1/2" thick flanges
1 1/2" or 1 5/8 Primaries
Electroless nickel and High Polish silver Ceramic coatings
No-fault Lifetime warranty
Provisions for O2 sensor and extended harness
All necessary installation hardware
Installation Instructions

The headers would retail for about $699.99 for the electroless nickel and $824.99 for the Silver ceramic coated headers.

If there is enough interest amung the community, they may very well produce the headers. Be sure to check them out here: http://www.gtpse.com/tog/

To me that sounds like a lot of work!! I am more interested in the easy stuff, like air filters, reprogram kits ect. I already have a race car, I don't think I would want to modify that much. The other stuff you can change back to stock easily.
If I were to purchase I would want to the ground horsepower and torque numbers from a dyno before and after.

might be interested......but in about 3 years or 36,000 miles, whichever comes first!!!

Their headers on the 3.4 LA1 make 19 whp, dyno proven. Safe to say it would be at least 20 on the 3500.

3500's have a slightly better designed stock exhaust system. But only the dyno will tell.

id be really interested

I doubt this was a continued project since the link doesn't work.
