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 didnโt like was it has a nice chrome tip on it, but the pipe is so short, it dumps out under the Jeep where you canโt see it. Not a big deal at all and is still worth it. It fit perfectly thoughโฆdown 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.

Cheap, makes sound and you know you want to.
AMAZING. It makes the 3.6l sound like it has some umph behind her. I am the type I want to hear my vehicles when im driving. The only time I could see some people not liking it is if they are above 4k rpm for long periods of time. For everyday driving and some fun spirited driving this thing is so nice. Deep bass sound at idle.

Great product
There's a lot of mixed reviews on this, but in my opinion it's great. Obviously it's going to be loud it's a muffler delete so don't be surprised. I have already took the resonator off so it would be a tad quieter if you have that still. It tucks up nice and you have way more clearance than that bulky stock muffler. I personally noticed a power increase, I have a 6 speed manual and was constantly going back and forth from 5th to 6th under 70mph ( 3" lift and 35") now I can run 55+60 in 6th no problem. 4 out of 5 stars just because I had to modify the hanger to get everything positioned to not touch frame and rattle.

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. ๐คฃ๐คฃ 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. Itโs 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, itโs 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.
