I just put a new TTI system on my 100% stock 70 Charger R/T. It is the 2/5" H pipe with manifolds and Dynomax Super Turbo mufflers. The mufflers have bad drone and I an looking for something quieter with no drone but the only thing I am finding that is a direct repacement (no pipe cutting) is Walker Quiet Flow 3 mufflers which I think are a OEM type muffler. Anyone else know of any other quieter direct fit replacements for the Dynomax 17784
