I bought a used Kakimoto muffler for just 50V$ a couple of days ago. It arrived today and i fitted it on the Mazda, obviously. I wanted to keep it pretty much stock but i made the first mistake. ¯\_(ツ)_/¯ Probably i'll end up doing something crazy. Well, at least it will be interesting. It sounds good, maybe still a little too loud, but it looks kinda good. It still needs some adjustments, because this is a random muffler from a Honda. I'll make it fit somehow.
