Does anyone know what DBI does the PC TI-4 run at???
My buddy said an 06 YZ 250f with a titanium powercore 4 got tested at 108 db at stonyford. Thats freakin LOUD right there!!! The Ti-4 is similar to the powercore 4
My t-4 would ring in at 106 - 110 depending on how accurately we could hold the throttle.
well all i have to say is thats loud! i am used two 250 2 strokes where they run at like 97
Yup, my T-4 on my 2002 YZF250 would actually leave my ears aching, if I revved it without a helmet. It was great for throttle response and jetted great, but loud. Don't know decible wise, but above 100 for sure.
