9000XL
I purchased this muffler, expecting an easier installation and the same great sound as the super pro street 9000. I had the original 9000 installed on a previous truck and absolutely loved it. The XL sound Is not even close to the original. It actually sounds as mellow as a 50 series flow. I love the sound of these mufflers and their quality, just wished I had knew how much "quieter" it was going to be and I would have selected the regular super pro street instead.

Amazing sound!
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.

Amazing!
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! -
Amazing sound
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!
