So, I bought a Rinehart slimline header pipe and their 3.5 inch slipons to go with it. Plan to install tomorrow and I'm not getting much help from Vance & Hines, probably because I didn't buy their exhaust system.

My question is, what V&H Head Pipe and Mufflers should I select on the FP3 to get a map loaded to use while I autotune it?

I have SE Street Cannons on a factory head pipe with the CAT still in it on my 2016 Road King. I used autotune and it did a great job. Just need a starting point for the new pipes.

BTW - I'm also putting a Fuel Moto breather on it, so any advice there would be appreciated as well.

Thanks in advance...

 

Call Fuel Moto. Even thought you didn't buy the tuner from them you're still using one of their products and I'm sure they're willing to help a customer.
