when looking for them one has to ask ones self a few questions .
is it practical for my elevation ?
meaning were they designed for your working elevation . save yourself some disapointment if you think pipes designed at sea level will work for a motor that has lost 30 hp due to high elevation physics .
pick a builder that most suits the occassion .
note weather it states used with modified motor only .
yes the r motor will benifit greatly with twins , hands down due to what doo did internally on it versus the series 3 motor .
we were excited till the chassi change on the xp and what it meant for fit.
.
there is a lot of room once you remove the front air box .but it does require the support plate to hold the light up there .
fellas i deal with have been working 2 years on the twins for this motor and the gains are there , even when fitted they deliver on 87 oct at sea level.
as you go up in elevation your going to have more to deal with than the guys oporating under 5000ft.
ask the builder were the target elevation use is .
they can build for the diminished out put of the elevation.
i know Greg at jaws can .
the others im not sure , about , but ask.
