So happy with it. Had it welded in place I'm going to do the other side next.

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.

More torque,More power!
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.
