Aluminized steel last long enough. Are you going to drive the 450+hp rwd car in the snow/salt? If not minor crap from summer roads will not do a damn thing to your exhaust. I ran a flowmaster 44 on my ranger for years. My buddy has a f-150 5.4L with dual flowmaster’s and it see winter and he isnt anal about cleaning his truck… no porblems still look new.
Flowmasters dont drone as much as FG packed mufflers. in my opinion from what I installed or ran myself.
BUT magnaflow makes all their shit out of stainless. you wont see them so just get the satin SS. The magnaflows a built very well, and I saw 2 FlowMasters welds start to crack… no MF’s had any problems for me so far.
Borla is nice, but overpriced i think.
I say run cherry bombs. it is a v8 afterall.
