mild steel sounds much better for V8's, much deeper gruntier note, stainless sounds tinny, its way too expensive the only reason its good is because it lasts for alot longer than mild steel, but are you going to keep your same exhaust for over 5 years? doubt it, then mild will be fine and even if you do have to replace it then its half the price of "wank factor" stainless steel
