      MPG YES!

      Comments about Flowmaster 817492 Force II Cat Back Split Rear:

      Best purchase ever. I had it installed at the local muffler shop.
      They said it was the best quality cat back system on the market. Great tone, not too loud but just loud enough. I combined with the K&N Air Charger Performance Kit. My MPG has increased by 6mpg. Throttle response has also improved. Idle speed went down from 900 to 500rpm. Also saw a decrease in rpm through out the entire band. 60mph=1400rpm. That must be where the extra mpg comes from.

      Bottom Line Yes, I would recommend this to a friend
