I currently have a Borla Catback exhaust on my truck with single in dual out tails. I have a set of 2 chamber flowmaster mufflers that I was gonna use to split the exhaust into true dual exhaust. Would I gain more power this way or would I lose too much back pressure? What are your opinions?

 

good question let me know when you find out i was intrested in splitting my flowmaster exhaust and gettinf two 40 series mufflers!
