From what I've heard and seen, the QS1 is around 93 dbs. Where the utility pipe is around 101dbs. It produces around 1/2 the power as well. Rubicon3303 has one and it sounds good on the trails. But from what he said and what I can imagine, it must be REAL loud in the neighborhod echoing on houses.
I'm going to get a utility pipe, as soon as my wife lets me spend some more money on the bike.
