So I sold this as a set awhile back and some how USPS lost one of them not sure how. I called Crane and they said they can grind a new exhaust cam and ship for around 200$. I have read up on the specs of this can and it is pretty close to stock. I am not really sure if you could run just the one or not and if it can hurt anything. I would do 80$ shipped in the continental USA. Any questions pm me or you can text me at 402-230-0451. Really want this gone my just take a crazy low ball try me!
