My OEM Catalytic Converter shipped quickly and on time. Althought I had a shop installed it, there were no issues or concerns with the direct fit of this converter. Price was good as well.

Good muffler
Muffler sounds good. While not drowning on the highway I did a muffler change while keeping 3 cats but removed resonator and it sound well.

Christmas present
Got this as a Christmas present in 23 finally put it on end of June 24. I deleted the old muffler all the way to the tailpipe and resonator. This glass pack sits right under the bed of my truck and gives an amazing sound to the exhaust note. Not loud enough to wake the neighbors, but perfect if you just want to enjoy the sound of your engine

Vrooom! With Authority
I was leery about scratch and dent on an exhaust unit. But man! I choose well! I had to snip a TAD off of 1 end that attached direct to the muffler and done! Beautiful fit and finish and equally loving the deep, tame rumble this beautiful Magnaflow exhaust added to my 2022 5.7 Hemi!

Had to modify but sounds great
This install went well took about 2 hours. Hardest part was getting back tailpipe hanger off as it’s in a difficult spot because of spare tire and the heat shield. Would’ve been easier to remove but I still managed. Also tail pipe didn’t fit to new muffler so I had to flare the tailpipe a bit to get it to slide over the mufflers pipe. Overall though good sound with a slight drone when engine goes to eco mode. Love the sound though!

2016 Z71 - Bama6566
Decent sound
It sounds very decent. Little quite at idling but when giving it gas she has a nice rumble. Only negative thing is the pipes weren’t lettered like instructions. You don’t need 14.5 extension for any Colorado. But instructions say you do go for crew cabs. Must only mean full-size trucks.
