not to osund stupid but for a 2004 XC SP what do V-Force reeds do and what would a dynoPort silencer do?? the sled is plenty fast not looking for mods just wondering what they would do because i hear talk about reeds alot and im still confused... although a piped sled would be nice

On most sleds aftermarket cans add noise and most often only slow the sled down. V-force reeds work well on bigger CC engines adding marginal h/p gains along with improved throttle response. On smaller sleds mental h/p is the biggest improvement along with some / little throttle response.
Clutch kits continue to be the "best bang for yer bucks" performance parts out there.
