      Sounds awesome, not too loud

      Only when cylinder deactivation is active it is louder than normal driving.

      Too loud, too much drone

      It’s a quality muffler and fits well. It is too loud for my liking. Worst part is the horrible drone when the MDS kicks on. So after 3 years, I’m finally taking it off for a little more mellow muffler. I’m sure my neighbors will be happy.

      Great sounding exhaust, increase in torque and speed. Need to add an air kit to lean it out a bit.

      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
