Sound Testing for Honda Civic Si Top 10 Exhausts

Click for more: dsportmag.com/social/
Testing the Industry’s Most Popular Exhaust Systems for the Civic Si
Considered to be one of the first go-to upgrades, choosing the right aftermarket catback exhaust system is an important step in every car enthusiast’s upgrade path.
Each exhaust system on the market offers a unique sound character, hardware, looks, and affects the car’s performance differently. You simply can’t choose one exhaust for everyone.
While OEM technology has reached an extremely efficient level, providing almost no restrictions after the downpipe when using the stock turbocharger, replacing the factory system is almost a must for every car enthusiast - especially on the Civic Si. The Si is one of the quietest performance vehicles on the market today, with nearly no character in terms of sound.
We gathered 10 of the most popular exhaust systems on the market and put them through vigorous testing. This will give you the data you need to make a purchase whether you’re looking for sound, looks, power, or build quality out of your new exhaust.
We want to hear from you.

@@dsport I’m lost on what to do for my 18 civic Si. I want an exhaust but I want to be able to control the sound to some aspect. I like how the stock exhaust sounds when it’s just a chill day or night. I was thinking a dump valve. That map exhaust sounds so good though lol.

[@NEO_Trojanmuldrop4]

I’ve always loved Borla exhaust systems. Back in the day I had one for my 2003 g35 coupe sport and it was the best sounding exhaust in my town. But the greddy sounds good too

Besides the greddy exhaust, what would you recommend for the quietest aftermarket exhaust? Had my eye on the remark exhaust, not too expensive, but still has fairly large piping and doesn't weight too much.

I stepped out on a limb and threw together a custom pipe on my civic. I got 3'' pipe with a Vibrant Resonator to a magna flow Y pipe to 3.5 inch tips. It sounds better than some name brands for a fraction of the cost. SOUND VIDEO ON MY CHANNEL!

Would of any of these fit on a 2019 Honda Civic sport sedan with a 2.0 liter non turbo I can’t find anything for it

These systems are for the Civic Si. It wouldn't fit because it's an entirely different engine.

Hold out on buying an exhaust for your sedan, the cost for the sound you get wont be worth it. Save the money for the next whip or pay that one down more.

[@yumanny8]

Why is there so much water coming out of the exhaust?

[@jamesmedina2062]

natural product of good combustion. On older exhaust sys the black carbon soot inside pipes soaks up the water so it doesn't run out like on new steel
