I just bought a 2007 jeep commander overland and I was wondering if there was kits to get dual exhaust? Has anyone heard of gforce chips and if there any good?

There are no dual exhaust kits for the Commander. However, I have seen dual exhausts on Commanders. It can be done but it is not easy.

Did a quick search, jcwhitney offers a dual exhaust but it's by heartthrob? Never heard of them.

Also about the chip, think about it, if it were that easy, cheap, and that great of results, how come those dont come stock or why doesn't everybody have them? I think it may be a snake oil and possibly might NEGATIVELY effect your engine. I'd stay away.

I think this is a generic kit. On a lot of auto parts websites when you put your vehicle info in you will get things that are not really for your vehicle. Also, read the description of the product. This also makes me think this is not really made for the Commander. Notice the last line of the description.


"DUAL HEADER PERFORMANCE EXHAUST SYSTEMS
  • Complete! Ready for fast, easy bolt-on installation
  • Aluminized, mandrel-bent tubing allows for better airflow
  • Fits most V8 and V6 headers on most vehicles
Connectors bolt onto most headers — no welding! Bullet-shaped, straight-thru glass-packed mufflers reduce backpressure to increase performance and give a low, mellow tone. Multi-fit connections ahead of mufflers and extra-long tail and side exit pipes allow easy installation on most vehicles with headers. 2-1/4" OD tubing. Reducers included to fit all connectors. Also available with turbo-type mufflers. Note: Not for any 4x4's or trucks with rear fuel tanks in front of rear axle."

Also, compare the underneath of the Commander with the diagram of the kit and you will see that it won't work.

I see what you're saying. I didn't read that far into it just did a quick google search. Looks like a lot of custom exhaust work would be needed. I think even my stock single exhaust sounds pretty good. A little quiet but at start up you can really hear the roar.
