I have been looking at Cat Back Exhaust systems to put on my 07 F150, and I can't decide which one to get. I have narrow it down to the Gibson, Flowmaster, and MBRP. My question is, which one will give me the most performance gain? I don't really care about which one sounds the best. Thanks for the help.

 

you would have to find the dyno specs on all of them. if it was me, i would whichever was the cheapest, most, not all, exhausts are built similar and the gains are close to one and another.

 

like ATOM stated without dyno sheets there all gonna be about the same.

 

Spend less money and let a welder do the work for you. If you are concerned about power, they will be able to do exactly what a big company does for less money and you are helping put food on their table.
