Is this a good pipe for my 450R. Im looking for an after market pipe, a good all around torq w/low end. Not for racing.

Any body run this pipe?

Are quite cores avail for this?

How loud is this pipe in dbs?

My friend had one on his YFZ and it was extemely loud. Power gain was "ok".

Dude,
I have an 05 450r whit the FMF Factory 4 and a powerbomb header,and at first it wasn't that impressive. But then i took it and cut it down to about 5 inches or so (really really short) and made a new mount out of my frame, and it seriousely opened it drasticaly. (and wow is it loud lol)

I have one on my yfz, defnitely loud, the have a quiet core and S/A available, but if you are looking for a good play bike pipe, I would look else where, I personally would look at an HMF or maybne the FMF Q series
