DB stock exhaust without baffle/spark arrestor

[2001-400ex'er]

Could someone please tell me how many Db the stock exhaust is without the Baffle/spark arrestor because i need some type of basis when picking a slip on-are there any slip ons that are near this loud?

If you worried about how loud you exhaust is gonna be, then get a White Bros. E-series, you can add disc's to make it loud or take out them to make it quiet. Done deal.

yes i agree. 4 discs is supposed to equal stock flow. i love my e-series.
