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

Perfect, Just Perfect!
This was worth every penny. The quality build is amazing and the sound is nice and deep compared to the stock! It’s not loud, just deep! Which is awesome!

A Nice Start
If you don't want to drop the extra money for the Megan Racing Cat-Back then this is the axle-back for you, this makes a boring drive less of a chore and make the car a lot more fun to drive around with. I suggest getting new exhaust hangers for this because the old stock ones make this one shake too much. I know the rating says it's loud, but it's pretty quiet but not so much where you don't hear a difference, it's a great exhaust note in my opinion. Great for young people to just start off their first bolt on stuff.

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!
