Sounds great
Mine came in good shape, welds were good. It doesn't sound like a fart can on a civic like some comments said. I had a cat back dual exhaust and it was louder than this pipe. It sounds good, deep tone at idle. Louder when you floor it but not bad at all. I recommend this pipe!

Fits 2016 JK and sounds great
Installed on a 16 Jeep Jk with the 3.6 It sounds nice. Not too loud but gives it a little noise with a nice tone. The only thing I didn’t like was it has a nice chrome tip on it, but the pipe is so short, it dumps out under the Jeep where you can’t see it. Not a big deal at all and is still worth it. It fit perfectly though…down to the exhaust hangers holding it. I would recommend.

Too raspy for me.
Item is as described. Good quality. Hated the sound. Drove it 100 miles and sold it. Spend a bit more and get a dual pipe with high flow muffler.

Sound and clearance
Gives my jeep a good sound. If you take it easy on the throttle it's not real loud. If your hard on the throttle it sounds like a mustang. 🤣🤣 Installation was easy. Made from good materials.

3.6 Jeep Jk. Easy install. Loud.
2015 wrangler 3.6. Easy install. If you take your muffler off for a day you will get an idea of how this will sound on your Jeep. It’s actually a little louder with this installed believe it or not. It is high clearance and tucked up tight. Only time it is going to sound good is if your are getting after it, Brraapin it up. Other then that, it’s kind of annoying. I will most likely find a way to quiet this down a little somehow and install another resonator or something. 4 stars - but know what your getting.

Fit and finish are Top Notch
Looks great, fits great high and out if the way. Jeep loses about 25 lbs. Sounds great at idle, but it barks pretty good from about 3000 RPMS and up. You can definitely hear it. Not sure how it would be on an automatic, but with the stick it's easy to upshift and quiet it back down

Nice sound
This is a quality product.... The instal was really easy as well.. The sound is great as well.. really not that loud until you get in the upper rev range 3,000 to 4,000 RPMs... But I like the sound...

Loud, but not always the good kind of loud.
I did the install on this, it looks nice, and really cleans up the back end from the giant suitcase muffler the JK had. The sound at idle is actually fairly throaty and pleasant. Even shifting through the gears on my 6 speed manual, everything below say 2800RPM sounds more or less like I'd expect. From about 2900RPM-4000RPM it screams like a rice burner, not pleasant. I'm thinking of adding a second resonator to take out that high pitched fart can sound. For what it is, it's a good price.
