Q: Should I use hangers on my Black Widow mufflers?
A: Yes, as of March 1, 2017 our warranty requires at least 1 hanger on the body of your muffler (not on the inlet or outlet tubing). Not doing this could cause damage to the muffler and WILL void your warranty.

Q: What's the difference between your Race Venom and Widowmaker mufflers?
A: The most obvious is the shape - Race Venoms have a square shape vs. the Widowmakers - which are round. While our Race Venom mufflers retain that classic/crisp hot rod sound, our Widowmaker mufflers are generally louder and, like all of our mufflers, help manage drone.

Q: My exhaust has only one stock muffler. Do I need two mufflers to get a more aggressive sound?
A: No, our mufflers are designed for straight through airflow, so switching to a single Black Widow muffler will give your car or truck a more aggressive sound over your stock muffler. (Note: our mufflers will not make a 4 cylinder sound like a 6 cylinder or a 6 cylinder sound like an 8 cylinder.)

Q: Should I use an X-pipe?
A: If you're running a dual exhaust system, we recommend an X-pipe (or H-pipe) for "ideal" sound results; however, an X-pipe is not necessary to obtain quality results. X-pipes can also be purchased through our web site.

Q: Which muffler is loudest?
A: Generally, the smaller the muffler the louder they will be. For that reason, our Neighborhater muffler is typically our loudest muffler.

Q: Is there a difference in sound between the Pro-series and the Classic-series mufflers?
A: No, our Pro-series mufflers are simply polished versions of our Classic-series mufflers. The sound quality, construction and internal designs are identical.

Q: Is there a difference in quality between your mufflers?
A: No, all Black Widow mufflers are quality welded and are backed by our Limited-Lifetime warranty.

Q: Which muffler is best for my car or truck?
A: All of our mufflers are universal and can be made to fit almost any exhaust system. Our 300-series are the least aggressive. Our 250-series are mid-range and our Race Venom and Widowmaker mufflers are the most aggressive. Visit our "Listen" page for sound samples.

Q: I have 2 1/4" exhaust pipes. Will your mufflers work for my car?
A: Yes, our mufflers are universal and can easily be adapted to fit your exhaust pipe. We recommend installation by a qualified muffler shop as additional fitting may be required.

Q: How many chambers are there to your muffler design?
A: Our mufflers do not have chambers. Chambers are created to channel airflow in an attempt to create a specific sound. Our mufflers have a non-restrictive, straight through hourglass design created by two sound deflectors that aid in pushing airflow out of the muffler at a greater velocity than upon entry.

Q: How long does it take for your mufflers to break-in?
A: Our mufflers do not use packing, so there is no "break-in" period. Because of this the sound will stay consistent throughout the life of the muffler.
