Using all the experience and R&D testing that went into the Q4, the next step was to create the ultimate off-road exhaust - the Titanium Q4. Sharing all of the advances found in the Q4, the Ti Q4 weighs less than most moto mufflers and measures below 93dB on nearly all models tested (no more than 96dB on any model). The best way to describe the Ti Q4 would be "less is more" - less weight, less noise, more places to ride. |
