Is it really worth dyno-jetting my bike?

[samchuck4]

I want to put a mtc stubby end can on my bike however i have been told that if i did want a straight through stubby i would have to look into getting it dyno jetted and get a performance air filter. Is all of of these going to make much of a difference to performance? Or is it easier to just get a regular exhaust

If you are changing the zorst you may need to re-jet it.
Only way to find out is to get the zorst and see what happens.

FWIW though, i had mtc pipes and zorst on my 1st zxr400 and it needed jetting.
