Not loud !!
Great Muffler if you want quiet . This is a very tame muffler !! Maybe a tad louder than stock on 5.7 Hemi motor . I don’t plan on keeping the muffler on my truck .. it’s just to quiet .. Black Widow makes a much better muffler .. imo

Noticeable but not too loud
If you're looking for a nice sounding muffler that isn't too loud I would pick this up. The finish and welds are top notch! I put this on a 2012 Jeep JK and it sounds very nice!

Not as expected
Being Borla I actually expected this to be louder, especially with the fact that I added in an X-Pipe as well, but to my amazement and pleasure it’s not loud. Sounds like an exhaust Chevy should have used on the trucks from factory in my opinion. Nice deep sound under acceleration and quiet while idle.

Beautiful Tone
Put two of these on my 6.0L swap. Long tube headers & x-pipe make for a beautiful tone.

Brought some life into my jeep along with a tailpipe, sounds way better than stock but not obnoxious for everyone else

Overall, it is a Borla product so a true stainless muffler (checked with magnet) and well made, however the unit I received definitely had some "built on a friday" vibes. One of the outlets was ovalized (not round) and the weld at one point dips into the pipe (rather than being a consistent bead on the outside, the weld bead sits on the inner flow-side of the pipe.). Won't affect performance but not what I want to see at this price. Additionally, along the case seam where the outer case meets up, there were a few razor sharp burrs that should have been cleaned off before boxing the muffler. (Definitely bit my hand pretty good when I first grabbed it out of the box!) So that's the reason for 4/5. Great Borla product, but my unit definitely had Ray Charles on the QC line ;)
