I think I had I had something similar on my 05 Chopper DT, didn't make a difference but the PO said it was necessary, forgot the reason.

I had so many different air breather on my Mastiff, lol. But yes I do have the RSD on the Bagger as of now. Here are a list and my opinions of the ones i can remember on the Mastiff:

1- Factory Breather w/ K&N air filter - 3rd best for performance and fuel economy - Kerker 2 into 1 and FSD exhaust
2- Big Dog 90 degree Spike w/Filter that came with it - ok, but spits and sputters at 80 mph or at any steady throttle - FSD Exhaust
3- Big Dog 90 degree Spike w-K&N Filter - ok, but lost numbers on dyno - Kerker and FSD exhaust
4- Big Dog 90 degree velocity stack w/filter that comes with it - Good, but filter needed to be better - FSD exhaust - 117 and 124 motor
5- Big Dog 90 degree Velocity Stack w/ K&N filter - really good performance after having to adjust carb several times kept hitting leg on it tho so changed it - FSD exhaust - 124 motor
6- RSD breather w/ K&N Filter - Very good had to buy a CV to S&S adaptor plate tho which made it stick out a little -FSD exhaust - 124 motor
7- S&S tuned induction w/K&N filters - Best for performance - FSD Exhaust - 124 motor

I believe there were a few more but nothing worth remembering....lol

Adaptor plates can be found many places but here one is:

Best for performance is the S&S tuned induction but are getting very hard to find (no longer being made).

There are several adaptor plates available that will allow you to fit a HD EVO style that opens it up to a whole lot of options.

The only bad thing about the adapter, is it pushes the filter further out, the RSD style already sticks out a lot and into your leg.

I just re drill holes
