Porsche 718 GT4 RS / Spyder RS SOUL Competition Headers (with Jet-Hot Coating)

I bought the full Soul Performance Exhaust System ( headers, over the axle pipes and the catback but it was a little too loud so I decided to uninstall the headers. These headers have less than 100miles on them. Usually there is a few months waiting list since they are made to order. The hp/tq gains are very noticeable.
