Update for those interested.

I went ahead and installed a catless quad resonated Xpipe. As expected there is noticiable smell, maybe too much. As for sound...it sounds good but there is rasp, yes, even with 4 resonators. Between 2500 and 3000 there is rasp. I will upload a video maybe later tonight.

I will leave the car like that for a few weeks. if I still dont enjoy it, I will add HFC and see if that helps with smell and sound.

Will keep everybody posted.
