It's difficult to tell from a video, but that modified 2bros sounds exactly like the FMF on our 250. Will have to remember this trick if she ever wants to quiet hers down a little.

One question I do have is are you running a fuel controller? I wonder how much the change in back pressure would effect the mapping?

Just like the un-modded can or even the stock pipe, theirs no difference in acceleration

i mean for sound purpose not like a 0-60 lol
