GReddy Supreme SP Exhaust | 2017-2021 Honda Civic Sport Hatch (10158212)

Very happy with this purchase. The exhaust defiantly adds a deeper tone but isn’t too loud. Install wasn’t too bad either. For the price, it’s hard to complain especially when the quality is great!

Finally installed this, and I have got to say, this thing sounds amazing. The first car mod I installed and it was pretty easy, and the fit was good and everything was straightforward. The exhaust sounds amazing, deep, and has a nice low drone while cruising on the highway. I wanted an exhaust with a nice low sound and a little bit of a drone, and this is the perfect one for me. It's not annoying and still keeps the car enjoyable. For the price, I think this is an awesome product and how the Civic should sound out of the factory.

I find this exhaust perfect pretty quiet with a deep rumble, installation was easy shipping was quick. Do recommend.

After reading previous reviews, this exhaust sounded like exactly what I was looking for. I wanted something with a good sound but wouldn't attract too much attention.
It does the first bit well! But I think it does the second thing a bit too well... It makes a nice sound, but not enough sound for me.
There's no resonator in the system but surprisingly there's no drone either. On the highway I can listen to music or hold a conversation with the people in the car without interruption which is really nice.

But when I'm feeling like pressing down the pedal, not a lot happens. Sure it's quicker on the acceleration, but it should be paired with more sound as well. If I'm playing my music loud, I won't be able to hear the exhaust which is a bummer. I find myself keeping the volume low to hear the exhaust :/

Don't get me wrong, it's an awesome exhaust with an epic low rumble sound! I dare say that it almost sounds like a Subaru 👀
It's fine for right now. I'm driving a civic anyways lol

But to be honest, if you're looking something on the aggressive side, I would definitely steer clear from this choice.
I like it a lot, but I don't love it. I wish it was just a tad noisier. But that's just me.
If you're merely looking for the performance aspect of it without making a lot of noise, than this is absolutely perfect for you.
I think maybe paired with a front pipe/ down pipe, it'll wake up the exhaust more!

First impressions of this exhaust was that it had a very nice build quality with thick tubing through the entire system. When it was installed I was a little underwelmed about the sound of the exhaust until I took it for a test drive. It's very sporty and has a great sound to it compared to many other exhausts on the market. It's how a civic sport hatch should sound from factory. Other systems can sound very ricey and throaty and loud with a high pitch but this exhaust has a really good growl at high rpms.
