dr.d vs. fmf Q exhaust

Recommended Posts

It depends on what bike it is, stock YZF is rated at 99 decibels, with the Dr. D Quiet-Core Insert it brings it down to 96db. The FMF Ti-Q is rated at or near 93db on most models. If your riding forest trails, get the FMF. If desert trails, then you should be fine with the Dr. D. Good luck.

QUIETER is BETTER, Period. :)

The difference between the 93dB of the "Q" and the 96 dB of the Dr. D is double the sound energy. :)

what bike do you have to put it on?? they both have a fairly close db level but if I were you look into which gives the nicer horse power jump.
