I'm flabbergasted. Good thing you guys are around to save people some heartache.

 

Hmmmmm I dont think I'll get that vortex insert (the last picture). Seems too restrictive

 

if you go to big gun's website, the vortex actually looks a little different, but the same general design, and they are not showing anything for the klx300 anymore.....strange...[&:]

 

The Quiet Core is a little bit louder than the Vortex insert, but FAR LESS restrictive (about 1.39 sq. in. opening versus 0.5 sq. in).

I've heard the stories about how the Vortex is a good temporary solution, but not a good choice for continuous long term use. I guess it causesa lot ofpulsating back-pressure, which over time fatigues the rest of the system and beats itself to death - figuratively and literally. (Get it: "beats itself to death"? Man, sometimes I just crack myself up! )

I must be mixed up. I meant this thing.

 

Yeah, that's the restrictive one. The Quiet Core is the one that's a little bit louder, but far less restrictive.

Here's an end view of the Quiet Core (The Race Core is similar, but without the baffles):

 

hmmm i dont think my bro's came with that one either. i'll have to double check. Thanks for the pics man.

 

Hows the sound of the quiet core vs. the vortex insert, im gonna get the quiet core over winter... is it a bit louder than the vortex?

I'm amazed that anyone buys this crap after all the problems people have had, but anyway I'll shut up
