    • 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

    • gives good ground clearance
product is pretty okay its just a pipe with hangers with a chrome tip with enough energy you could make this thing with stuff off the a shelf at autozone but it worked out okay :)

    • 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. ... show more

    • 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...

    • Just buy it!
The media could not be loaded. There is nothing more American than throwing that bulky suitcase muffler in the scrap pile and letting that Pentastar breath! It’s definitely on the louder side of exhaust but hey beats shelling out 95k for a 392 wrangler! I have a six speed manual in my Jo so I can make this thing absolutely scream!!! Or just slow roll and it has a nice growl. ... show more

    • A little noisy but fun
Easy to put on lower weight than stock hard to not want to throttle it up!

    • Pretty good if you have a manual!
I wanted a little more sound.. I went into this with no V8 truck expectations. You won't get a V8 truck sound out of a V6... Just won't ever happen. The note is a little raspy when going through the gears and then mellows out. Does NOT sound like a Honda with a weed eater muffler !!! I would have liked a deeper tone but not bad for my first real mod. ... show more
