Ultra Classic 2008 - Thunderheader

Hi guys, writing from Italy.

I just found a good deal for a full 2 into 1 thunderheader an I think i will go for it.

now the options:

- thunderheader with stock intake with no remap
- thunderheader + open intake ( big sucker , etc) + no remap
- thunderheader + open intake + remap/ external tuner

As I do not need to do wheelies or extra performance but only the sound, what's the best option for me?

is it safe to put the exhaust without external tuner or ECU remap?

thanks to everyone in advance

Agree #3
Your stock bikes already lean and you’ll just be making it more so with your header and intake.
You and your bike won’t regret a good tuner.

If money is no issue then #3. Properly tuned will give you a smooth, cool running engine with more power than stock.
If money is an issue then #1. Not ideal but should work with no issues.
Definitely not #2. #2 will be very lean, run hot, poor power, poor mpg (or is it km/g?).
