I have a 2 pair of stainless marine proformance dry exhaust, that has maybe 2 hours of use. No scratches or rust, just dust from sitting. They fit big block chevy engines. They cost $4450 for a set new. I would sell both for $7000 or $3750 for 1 set. (Obo)
You can look them up on their website. Won't let me post a picture or website.
