    Comments about Dynomax Mufflr-Ultra Flo Wld:

    These Dynomax VTs fit perfectly on my 1995 Corvette ZR-1 to replace the stock mufflers. They are free flowing and straight through designed, but have no drone or resonance and sounds perfect for me at wide open throttle. They will be too quiet for those that want attention and think that loud or noise makes your car have more power. I have yet to dyno them, but there is no question that these mufflers will out perform stock. Are there better mufflers? Maybe, but this is the ultimate solution for those wanting power, nice sound, but not loud and obnoxious. It is so quiet for normal driving until you open them up. I must warn that I replaced my stock resonator with a Magnaflow Tru-x muffler so that has contributed to how great my system is using the stock pipes. I am 100% happy with these mufflers and only time will tell if the valve technology lasts. With lifetime guarantee and price from Advance Auto it was worth taking a chance.

    Comments about Dynomax Mufflr-Ultra Flo Wld:

    Ihave a 1974 260 z Datsun with a small block chevy, mildly modified engine, about 330 horse, cam, headers, holley carb, the usual stuff. I have spent a wad of money on mufflers and pipes. I could not get rid of the dang Drone. There is not much room on a Datsun for mufflers, so I had about given up. Till I saw these. Dynomax guarantees the sound, so I bought em. I have no more drone. These actually work!!!

    Comments about Dynomax Mufflr-Ultra Flo Wld:

    I have this muffler installed in a 1998 Audi Avant wagon with a 2.8 V6 engine and with the sport muffler, it had a heavy drone at highway speed. With this new muffler, this has gone away, and peace and love of my stereo is back.
