My opinion: it needs a remap, even with the stock system.

That said, I personally wouldn’t hesitate to fit a slip on pipe without any mapping changes. If a slip on was what I wanted.

What are you hoping to achieve?
Search these forum topics and you’ll find there isn’t a performance gain from slip on exhausts.

 

Hi and thank you so much for taking the time to help me

Im not looking for performance gain at all, i just want better sound but someone told me that if i put a slipon on my bike and DONT remap i will lose Power?

Again thank you so much
