Hey guys - so I've had the Remus exhaust (including front pipe) installed for the 10 days or so and wanted to write a review. See below.
Background:
This car is my daily driver that I commute with 1 hour each way and that I regularly take on 300+ mile drives to visit family. I also have a dog with a severe anxiety problem where loud noises are really bad for her. I factored all of this when I was shopping for an exhaust system. I did not want drone and I wanted something that I could adjust the volume when I wanted. Remus fit what I needed.
Product Overview:
If you are not familiar with this product, it’s a 3” stainless exhaust with a Bluetooth-controlled valve that increases or decreases sound based on what mode you choose on a little wireless remote controller (see video at end of post). There is also an iOS and Android app which can control the exhaust automatically based on engine RPM; you can basically recreate “vtec just kicked in yo” if you wanted to. The electric valve is on top of one of the exhaust outlets in the back, and to provide electric power to the valve you splice into one of the power wires running the lights. There is a small computer / brain that sits where the tire repair kit is under the floor in the hatch.
At the exhaust’s quietest setting, it is as quiet as the stock exhaust (which is pretty quiet) under most driving conditions and there is no drone. If you really stomp on the gas it is louder than stock.
At the exhausts loudest setting (100% valve open), it is VERY loud but only when you are on the throttle. There really isn’t any drone either at 100% open unless you are trying to accelerate in 6th gear on the highway doing 65 mph. If you are not prepared for the sound of 100% open, it can actually catch you off guard when it ramps up (it’s that loud). It’s like “ok this is loud, this is louder, then BAM this is scary loud”.
I drive with 100% open when I’m out for a spirited drive or when I want to make myself feel like a race car driver. For normal commuting I keep the valve 30% open, which is plenty loud but not obnoxious. When I have the wife and dog in the car or when I’m driving late at night through our neighborhood I drive at 0% open because I'm a considerate human.
The Exhaust’s Sound:
On all settings the exhaust gurgles, pops, etc. (especially when decelerating) and just overall sounds aggresive / mean. The exhaust also has an audible “turbine whirling” sound to it from the turbo when you rev the engine and it returns to idle. It sounds pretty dope.
Cold starts have made my mornings something to look forward to with the mean growl, especially at 100% open (see video at end of post)
The exhaust is a bit raspier than what you traditionally hear from 4 cylinder Japanese engines. I personally like the sound – it’s almost like Remus tried to put a bit of a European spin to the Japanese 4 cylinder sound (if that makes any sense at all), especially given the European heritage of the brand. It’s not a “fart can” sound like the Hondas of old.
EDIT: Remus developed the sound for the exhaust in an acoustic chamber that costs $12 million (see Remus's post further below in this thread about their sonorous sound chamber with pics).
Honestly you can’t really capture the loudness / tone / gurgles / pops of any exhaust in a video unless you are listening to the video with some high quality speakers (i.e not headphones / not cellphone). See some videos below at end of this post.
Note: I also have the PRL catted downpipe installed.
Power Gains:
I didn’t get a chance to dyno the exhaust on its own (I did dyno it with all other parts and a tune and achieved 372whp / 385 wtq; see my separate post here: https://www.civicx.com/threads/type...-wtq-products-review-prl-remus-ptp-usr.30111/), but what we did find was that there is a 7hp difference between having the valve 0% open and 100% open. Max power was at 100% open.
Price:
It’s quite a bit pricier than most other exhaust systems out there for the FK8, and a big reason for that is the Bluetooth functionality. I love the flexibility to make it quiet when I want and racecar when I want. For that, it is worth every penny to me personally, but may not be worth it for other people.
Conclusion:
I love the exhaust and would buy it again if I had to repeat history. Thanks again to Mike @REMUS USA for getting it to me when I needed it and for @PRL Motorsports for the installation.
Videos:
See below. I suggest listening to these with some real speakers (not your iphone headphones or your phone) otherwise you really can't hear the tone / loudness and it just doesn't sound as good.
