where are you looking for hp. top end, mid or low. i am afraid if you could even find twin pipes for that sled it would make it extremely peaky in power, meaning you will have to hit your clutch dead on or it wont make the gains at the track. it might become very fussy also, its no fun to have to rejet every other day just so the sled runs right. the best you could do for trail is gear down a little bit and clutch it. there is alot to be gained in a good clutch kit. for the hp you might be able to set the heads down a little to make it a 92 octane only engine. but check your jetting and watch long lake pulls.
