Who has the Magnaflow Catback?

[flya727]

I just had my local guy put mine on 2 weeks ago. He used a single inlet with dual outlet muffler and 2.5 inch dual pipes out the side. It was a tight fit on the left side but it worked.

I just looked at Magnaflows website and the only system they show for the ST has just the single exhaust. Anyone here have a system like mine? I love the extra power and the sound is very nice on startup and quiet at cruise(for a performance exhaust!). Anyone have any info on increase in MPG on long highway trips?

Thanks,

Rick

Rick,
I wouldn't look for a huge mileage increase simple because the factory makes a fairly free flowing exhaust setup now, for a stock vehicle. So typically a stock vehicle (Ex.)with an exhaust will see a 5-8hp increase. If the vehicle has heavy bolt on's you will see more,only because the exhaust is really starting to work by moving the additional air.
