## Customer Reviews

### ⭐⭐⭐⭐⭐ Better sound than I expected from a glasspack.
*by U***E on January 13, 2013*

This muffler is replacing another red, straight-through muffler that I installed on my Durango about 8 years ago. While getting 8 years isn't horrible for a $30 muffler, the previous unit required bandaging and patching several times and I decided I didn't want another painted muffler. This one is about 6" longer than it's predecessor, so it's a little quieter but the tone is just great. My Dodge is a hauler/work truck, so it has no carpet and at highway speeds, the old muffler had a drone that was kinda annoying...this is almost pleasing even without a tailpipe and an angled tip. Hopefully it holds up better than the old one.

### ⭐⭐⭐⭐⭐ Oh Yeah!
*by R***K on February 3, 2017*

Paired this with a Magnaflow converter and gave my Truck a nice, deep, throaty tone. Sounds good at cruising speeds and no "drone" sound at all like experienced with other brands. Put 'er to the floor and the sound is bad *ss.

### ⭐ Rattles!
*by M***A on February 21, 2024*

Installed this on a 2015 4runner. Great sound, easy install...until the rattle started. It was difficult to isolate. For months I heard it, then didn't, then did. Finally, after checking all the connections, heat shield, etc., I determined it was coming from INSIDE the muffler. Warranty is one year (purchased 6/23), but I can't return for any kind of refund after 90 days?!Update: it took 2 MONTHS for a “customer advocate” to contact me via email. By this time, the rattle was incessant and LOUD. I had already ripped it out and replaced it. Terrible customer service. Dropped to one star. Waste of money.
