We have had many use the JBA mid-length headers with 3" collector with many aftermarket K-members and even stock. We also have our JBA shorties and they will work 100% but they have a 2.25" collector so you have a smaller outlet on the headers. Check out the mid-length images below and if you need any additional information please let me know.
