I have a 2010 Street Glide with the 2 into 1 exhaust. if I install the V and H Twin Slash 2-into-1 Slip-on 16777. Do I have to have the bike remapped or install a Power Commander or something liek that. The performance of the bike is fine with me. I just want sound.

 

I guess no one has a clue, Thanks anyway.

 

you'll be fine. The limiting factor should still be your stock airbox.

 

Thanks for the info. Just wondering since Harley added the cat converter for 2010.

 

What my dealer told me is that the EFI has some room to allow for the differences in exhaust. I hope you don't have to. I am looking really hard at the SuperTrapp Super Meg. Don't know if I'll worry about ditching the Cat or not on it. Just leave it there for now.

 

Again, the amount of airflow that will be restricted to the motor should be because of the stock airbox left in place. What little you may gain from the aftermarket exhaust will be taken care of with the adaptive learning of the ECM. My $.02 anyways

 

I just added new exhaust on my 2010 Street Glide... I added Big Sucker Stage 1 Kit and V & H fuel pack. I was told I would need it for the summer months. My .02

 

Dealer told me I could change the mufflers on my limited and not worry about the ecm until I changed the breather.

 

I'm still patiently awaiting those new 2/1 headpipes from jackpot...

 

Personally, I think it's a good idea to remap whenever you change the way your motor breaths in or out but no, you don't have to with just slip-ons.
