I recently purchased this for my 2005 G6. At first I was going for looks and figured it would do nothing performance wise, but I was completely wrong. My engine now runs a lot smoother and it actually sounds like a v6 now. I have also noticed a very slight change in gas mileage. It's nothing major but I'll still take it. Overall a great investment and well worth the money.
