Just ordered Cobra header pipes, K&N air filter kit , and the Dobeck tuner. Looking forward to getting it all installed. I haven't ordered mufflers yet but looking at the 4 1/2 inch Cobras. It's all for my 13 Ultra Limited.
Got the Cobra pipes installed with the K&N RK3930 air cleaner installed Monday. Installed the Dobeck tuner installed this morning and waiting on mailman with the 4 1/2 inch Cobra mufflers. Noticeable sound change with new head pipes with stock mufflers. I will update shortly when it is finished.
