I was curious if anyone could help me with purchasing a Megan Racing Catback exhaust, I had a few questions. I was looking for an exhaust that's slightly budget friendly and gives a deeper but not obnoxious sound. This seems to be perfect for what I want to do, however there's a few different places that you can purchase is and some of the listings say "Drift-spec", what does that exactly mean?

Also, would I need to purchase a Y-pipe in order to get the deep sound or would I just need the Catback exhaust, if anyone could help me out that would be great, thanks for any advice
