Are dynomax super turbo mufflers worth the cost?

Oliver, I have two 17748 Dynomax mufflers which are offset center and are the old Super Turbo "Hemi-sized" mufflers with 2.5" inlet and outlets and they work great.

The bigger 17769s are higher flowing and sound pretty much the same and work great as well. They are big mufflers with 3" in and out and large case units at 5.5 by 11". They are tougher to fit under the cars but you can do it!
