With my warranty about to expire next month I'm looking at buying downpipes and a Y-pipe (catless). There are many options to choose from with big differences in price. My question is, would cheaper versions really differ that much from more expensive ones? E.g. less drone, etc. I'm leaning towards going for more affordable options as I'm not convinced spending double/triple would make an arguable difference. Or am I mistaken? Thanks for your views.
