Hi, I have an opportunity to buy this cat-back for 400 new in the box but I have to act fast. can I get some feedback likes or dislikes. Thanks
2005-2009 Mustang GT/GT500 4.6L/5.4L w/Magnapack Magnaflow Exhaust

as far as performance upgrades I've only done Steeda under drive pulleys, C&L street cold air, and Diablo boxed C&L tune with 2 degrees added

I replaced my plugs a few months ago with the Champ 7989 1 piece plugs and my gas mileage went from 18 mpg to 11 mpg around town. Anyone else experience this too?

That's a good deal for the magnaflow magnpacks. I had that same set-up and I loved it. Nice deep tone. It will go w/any midpipe. I had it with a prochamber and hi-flow cats.

No benefit installing catbacks over axlebacks on the S197's unless the price is = or less than the axleback for some reason.

No input on the plugs/mileage issue.

Yea this is cheaper then the axle back too

With this set-up you have to use the OTA pipes with the axlebacks. The axlebacks that come with the kit will not work with the stock OTA pipes.

I have them on my car and love them.
