I'm reviving an old thread because it is the most relavent one that came up in my search.
I'm looking for a set of true duals for my '08. I got the fullsac kit....three tuners have said that the O2 bung is in a bad spot (should be on the curve) , most of their sensors wont screw in as they are too long. So it's going to get sent back....(more to that story!)...that'll teach me to try and go the cheap route.
From a performance standpoint the Basani seems to be the best ...but I am thinking that the 'double back' on the rear cylinder would all but negate the the removal of the 'leg warmer'.
I have V & H Monster Ovals and am keeping them....so I'm leaning towards V & H...but will have to consult with Russ @ Lonewolf after the long week-end.
It has probably been a while since you guys did this upgrade...so there should be more than a few experienced opinions out there.....any specifically with the Monster Ovals?
BTW: My Ultra is a 103, Baisley heads, 254 cams, A N Big Sucker, TTS.
