Pypes A body exhaust or Summit Which one should I choose?

Go stainless , never have to worry about the pipes again , unless they are a very thin wall cheap stainless . Had a cheap set of stainless headers rust through in 10 years , they were very thin 409 and never driven in winter or rain . Rusted from inside out . Good stainless will last , had a Borla system on my explorer for 7 years and 480,000 km of winter and summer driving , pipes were only thing not rusted through on the truck !
