Python pipes on '08 Street Glide

Can I just swap the pipes? Will the EFI adjust with just the pipes installed?

Yes you can change out the Slip-Ons..
Will the ECM adjust for it... NO

RE: Python pipes on '08 Street Glide

On the '07s you could change over to most slip-ons with out too much neg results...
You're not going to gain performance or make it run any cooler by doing slip-ons just going to make it louder.. And you might reduce your lower end performance a bit (depending on how free flow the system is your changing over too)
Being an '08 - little or no info is really out there yet.. Except for the fact and it's going to be months before they get HD & Aftmkt Management systems out on the market... And if you do change out the Slip-ons... SAVE YOUR OEM mufflers... Ya never know what EPA may due...
