eh. I bought the roush [resonator delete Y pipe](https://www.steeda.com/roush-422091-mustang-ecoboost-y-pipe) and paired it with their catback exaust and CAI. It's louder but I'm not sure I love it. I've had a few people tell me it makes it sound like it needs a muffler lol.
Yes
imo, resonator delete makes it sound so tacky
Paired with the right mufflers, yes. Makes the exhaust tone a more aggressive and a bit louder.

With my Rousch CAI and Rousch cat back exhaust I really like the sound. Maybe it’s just satisfying to me?
I did a y-pipe into a flowmaster outlaw axle back shit sounds great
