1.8 Maxim Works header + JoyFast innovation Catback

Hey everyone im selling my na and putting my stock exhaust back on it. Removing my imported system. Wonder what these are worth i know ive seen maxim heads go from anywhere between 200-500. Mine may have a flange leak stated in a translated auction, but i didnt notice anything or check very hard. As for the Joyfast catback I haven't seen one sell ever in the states so i pretty much have no idea. Mazda roadster has them new for $1000 mine is in pretty good condition just needs a good clean.Attachment 18256
I plan on selling them both here in the next coming weeks Thanks
