Yes...
And that is a long story... it seems like if I decide to change that it will cost me a lot: they kind of screwed up welding portion of the installation and now the whole thing is welded at the inlet of the resonator, meaning that upgrading it would become a problem.
It would be easier to remove it completly than putting a highflow in there.
(wow.. I never thought about that... maybe it is faith... maybe I should just bypass it... no resonator at all)
