Nice breakage..
Both times I broke a birf it made aloud poping sound and not only that it just broke the cage kinda gay. Id rather have a quiet pop and shattered birf just for the kicks of having one shattered.
Yeah, I expected something louder, kinda like when my rear 3rd blew up, that sounded like a damn grenade!
sweet man im suprised you got as much out of the stock birfs as you did.
So am I. Guess I'll see how long my second set of stock birfs will last.
