I have my bike tuned for a 2 into 2 exhaust but I just ordered a thunderheader for my bike. The question is when i change my exhaust do i have to get it tuned right away for the 2 into 1? I know it will have to be tuned but will it be fine to put 100 miles on my bike with the same tune? Or will i posibly be fine without getting it re tuned. Thanks for the help.

 

You'll need to re-tune it and I don't believe you can hurt it by riding it to the wrench or dealer that's going to re-map it for you.

 

Get it tuned, no problem with riding to the tuner...
