This muffler is sold under several different brand names around the interwebs, and yes, some owners have reported droning (mostly while cruising at freeway speeds). Do a search, there are a lot of posts and several different approaches to reducing or eliminating the drone.

Whether any particular drone "fix" will work for you is impossible to know because everyone has a different perception of drone and what level is acceptable and/or bothersome. This is an instance where "your mileage may vary" is a truism.

If you can afford a $250 gamble that might not pay off, then I'd say go for it because the exhaust will sound 100% better.
