magnaflow/urd etc vs random muffler shop 3" exhaust?

was just wondering what makes those exhausts worth double the price of the local muffler shop building you one. obviously one benefit would be that they are stainless over the steel. i live in a warm climate, rarely ever get snow so i'm not as concerned about how it would hold up as i would be if i lived back in pa still. so there's that one benefit that i could think of





disclaimer...it's 4 in the goddamn morning and my insomnia is kicking my ass which led to my mind wandering onto this topic

 

1. Quick and easy bolt on job rather than measure, cut, bend, weld, fab etc and is bespoke for your vehicle
2. Higher quality materials = much less chance of a material failure (cracks, corrosion, crap welds, etc)
3. Mandrel bend tubing, unless you go to a pro fab shop a mom and pop shop will not have a mandrel bender
4. You can say you diy'd it.
