The stock header has the cat removed. These were on a 2011 ultra classic. Header is from 2011, the slip ons are a year old. Im puting a bigger motor in my bike and going with a 2-1 pipe. $300 or best or trade. Also have other parts. All open for offers or trade. Id let all of it go for a set of stock 13 inch 12 way adjustable shocks off a newer ultra.
