05 YZF Slip on Exhausts? Advice on what to buy

Ok price is no problem.. I am looking to Keep the bike fairly quiet or a lil louder than stock is ok, but im not looking for full out Moto loud.. And a performance plus is nice.. Weight is not an option, I dont see my self buying Ti to save a pound or less..

So far I kinda have my eyes set on the FMF Q2.

I am still learning how to ride a dirt bike ( 23yo.. about time I threw a leg over a bike )

Why a new exhaust over the stock one? Cause within 30 mins of my first ride i found 2nd gear and rocked the twist to far back and stood the bike on end.. I would like to thank my fox chest protector for the protection from the rocks.. The bike faired worse.. I was able to bend the exhaust back to a semi straight shape. I used a lil JB weld to seal up the cracks in the alum.. Oopps... Eh.. no bike shops were going to be open the next day and damn it.. I wanted to get back on the bike and ride.. so that worked for a quick fix.

But now i need to replace it.. and i was planning on upgrading the exhaust anyhow.. just not this early..

I have looked at the FMF's and White bros Dr D and Power pipes..
I never found any magazine shoot outs or Charts on the exhausts websites.. So word of mouth is what i will have to go by..

umm

Someone pls...

I mean some of you must own a FMF or Pro circuit / CMF / White Bros Pipes.. It doesnt have to be on a 450yzf.

Just Are you happy with your purchase does the pipe deliver what it said it would.. How is it holding up, does it feel cheaply made??
