they just have a much different sound. not really about which one is better quality. the magnaflows usually are all stainless steel, while flowmaster uses aluminized steel, but honestly its not going to make any difference. they'll both last the life of the car

 

i was going to do flows for the sound of them. the magaflows arent as loud. but i have a upr catless X on the way and leaving the magnaflow catback on there and see how it sounds. by my guess is it will be exactly what i want. scream a little louder but not annoying and little drone.

as it is not there is very minimal drone with stock 2 fton cats stock H and magnaflow catback.

the X im guessing will just give it more sound and maybe some seat of the pants pickup(but not going to be alot) lol then the PP 75mm and plenum are going on as well.( know all about everyone saying 75mm is too big but i found a real good deal off craigslist for the pair)
