Installed this on my 5.7L Hemi with factory cats and resonators. Sound is beautiful, just the perfect loudness of bubbly growl! Very happy with the results.
My husband was very surprised with the quality and sound! He said it was much louder than expected.
I myself was also very impressed.
It sounds amazing!
My truck has never sounded better. The only disclaimer is to be prepared to lower your MPGs a few numbers for all the heavy acceleration you’re going to do. I can’t get enough!
