hey bud....simply drilling the pipes with stock filter,you do not need any changes to fuel control...VenomousSVT said:vmodded pipes are hollowed out with the baffles removed.. drilled pipes have the endcap drilled 8 times so that more sound can come out
once again you are going the same route I am aiming...new bike will get drilled first,for better sound only....there is a huge thread in the how too section about this....and all have said no changes needed...
then I will do my own Vmod and filter,and add a PC3 at that time...then later on I will be going to a thunderheader....love the sound and performance of that pipe best.
PS:I found a set of the H-D drag bars instock!...hehe
I just noticed you said toppless...you might just want to go ahead and Vmod your pipes,cause there are lots of maps for Vmods with topless Im sure...
plus with more air in(topless) and not as much going out(without Vmod just drilled) you are not gonna be gaining much perfermance if any....Id just self mod them for now,till you get your pipe.
