It’s one of the most quiet options, had it on my integra with the TSP downpipe & PRL front pipe. The tone was nice and the pops and bangs were there but not obnoxious.
Not sure if you're still looking, but I'd second the Invidia. I put the Invidia N1 on mine last week, PRL intake, stock dp and fp, but man, unless you're gunning it, it's pretty quiet. It's a deep tone, a bit loud at take off but pretty quiet the rest of the rpm band until about 4500, no pops and bangs from mine, but burbles aren't uncommon. And if it's still too loud for you it comes with silencers as well. The Q300 I believe is a bit quieter, but I went with the N1 as I'd heard it in person and could only find clips of the Q300 online. I had planned to put the silencers in it originally, but after the first 200 or so miles, I didn't feel the need to put them in, it was plenty quiet. The first 200 were admittedly pretty loud, but it was fun!
