I been very skeptical in buying exhaust for my 2021 civic hatchback Sports touring. Reason are because i have downpipe and front pipe so i knew that whatever exhaust i put on would be loud but my main concern was the sound. Didnt want to be raspy fart can. I went ahead and spent the money on this and i DO NOT regret it. Yes you can buy alot other cheaper exhaust but none will compare to this one. Super deep, ZEROOO rasp, buttttt the drone is bad at low speeds, 30-40 mph. Again i have downpipe and front pipe but if your stock and put this on, you will not regret it at all, probably zero drone. Loudness id say its like 8ishhh/10, but with stock downpipe probably like 6/10. All my friends were surprised on how good the exhaust sounds. If you want deep none raspy sound this is the way to go.
