Product Details

Silent Hi Power Series Exhaust Systems by HKS®. Silent Hi-Power mufflers offer high performance and sporty appearance with the added benefit of reduced noise levels making it the best choice for more mature enthusiasts. Silent Hi-Power mufflers are constructed entirely of SUS304 grade stainless steel for high lustre, long lasting performance. For certain applications, HKS has introduced the "Silent Chamber" which removes a lot of the lower frequency noise that can often be heard into the cabin even when cruising. The silent chamber removes this uncomfortable noise but due to its closed end design, only a minimal amount of exhaust gas flows into it, meaning that the disruption to exhaust gas flow through the entire system is minimized and there is no harm to performance.

Straight structure has a characteristic that is easy to eliminate high frequency sound. However, it is difficult to control low frequency uncomfortable sound that can be heard in the cabin. Silent chamber can reduce this low sound. In addition, because of the closed inside structure, exhaust gas does not through inside silent chamber and exhaust gas resistance is less. Therefore, there is no performance difference even silent chamber is equipped.

Awesome Exhaust Awesome Service
Exactly as advertised, bolt on cat back exhaust system, comes with all the hardware. Instructions are 100% Japanese, but it’s three pieces, some bolts and some gaskets. It’s self explanatory. Sounds great, while not being overwhelmingly loud. Definitely recommend.

Perfect for Daily Driving!
I couldn't be happier with this exhaust system! Installation was very simple, and it's obvious that this system was carefully engineered and well made. It provides a good amount of sound without being obnoxious; there's even some little crackles when upshifting as well. The product description says that this exhaust system won't fit on models with the CVT, but the stock exhaust systems for both the manual and the CVT are the exact same, so there weren't any issues there. I highly recommend this exhaust system to anyone looking to spice up their daily driver!

Great Sound!!!
Highly recommended for anyone that wants a little boost to performance, nice look, and perfect if you do not want it too loud. The Best part is it only took me about 15 minutes to install including the time to put the car on jacks.

Excellent
This is the only exhaust upgrade I'd recommend for Fit owners. It sounds amazing, looks good, and the performance boost is very noticeable. What's the exhaust note like? Well, I'll recommend videos which don't quite do it justice but I can tell you it's great! You get a great sound when revving the engine in pretty much any range, but at normal cruising RPM or resting RPM, you don't hear it quite as much, which makes this exhaust system great for long trips. That said, it is significantly louder than stock and a lot more professional-sounding than some little muffler you can pick up for 50 or 100 bucks. If you copy and paste the name of this product into YouTube you'll find videos of Fits being started, revved, and driven with this exhaust system installed. That said, it sounds a lot better in person, a LOT better. If I could give this product 10 stars I would. Also, since this matters to some, the product did come with a sticker! :). If I ever get another car, I will look and see if HKS has exhaust systems for whatever I end up driving next, before I buy from any other brand. I would recommend this to anyone!

I Like It And It Looks Really Good
The installment was very easy and simple like 30 minutes or less, I thought it was going to be a little louder, because I seen some of the YouTube videos of it they were louder, but it’s OK.

Pretty Good
it came in great quality, I love how it looks the sound is pretty decent it made my car louder but not crazy loud, but what do you expect from a civic lx. the picture is a little misleading, it doesn't come with everything in the picture, it only comes with one piece but it fits perfect into my car.

Excellent Product, Quality and Service.
I have been wanting to upgrade the exhaust system on my 2016 Subaru Forester for a while. I was in the process of heading to my local muffler shop to see what was available when I found this HKS Legamax Premium series muffler. Reviews on this muffler were limited but definitely a quality ss 304 performance muffler. I had to have this only one in stock so I placed my sales order and received it two days later. When I removed it from the box it was exactly what I thought it was going to be. Took less the 15 mins to install great low tone sound drone is manageable as long as you leave the resonator on. Very happy with this purchase.

Nice Sounds
Loud below 5000 rpms above that are quiet. I would recommend a header or down pipe with this
