i was just wondering what u guys thought of having dual exhaust from the cats back im going to keep the oem cats on. then going to a 2.25 pipe with cherry bombs glass packs out each side of the truck i have a 2005 ford f-150 5.4l . will there be any power loss or gain any mpg gain or loss? any codes? what will it sound like.

 

I think it would sound nice. It wouldn't be super loud because you still have the OEM cat in the truck, but still nice sounding.

I think you would notice a minimal power change and mpg change.
