Both my 2000 and 2005 arrived with FMF Gnarly pipes. The 2000 is an XC and never had a screaming top end, but low-end and mid-range power is where that bike shines. The 2005 is an EC (with the dual map ignition) and stock, it would scream on top. Now with Ron's cut head, it's a beast down low and I tamed it with jetting and gearing. It's so tunable, it allows for a true do it all bike.
