Hello all,

I'm new to the forum and I have seen many questions in regard to exhaust so I apologize in advance for this question.

I have 2014 CVO RK and looking at replacing the headers with S&S Power Tune Duals but keeping the stock SE muffler. My mechanic says I will not have to retune the ECU since I am using the stock mufflers. I was going to replace the entire exhaust but he advise me to just change the headers and keep the stock exhaust. I'm more looking at increasing the sound of the bike and getting rid of the catalytic converter. He said the SE exhaust is a good exhaust. I got the CVO to avoid a lot of customization and hate to waste money when I spent $$$$$$ on a CVO.

So if I go the route of S&S headers and stock SE mufflers, will I need to retune and will there be any benefits?

you could just add FullSac CVO Power Cores and Screens ..... that was what I finally decided to do and I'm extremely happy (side note ..... I also used FullSac S/S DX pipe w/ 2.25 cores)

yes a tune is widely suggested .....

X2. Went the Fullsac route and love it. Changing out the head pipe will help with heat but will do little to increase the sound. I like the look of the CVO mufflers so did the power cores in the stock cans. When you see how restrictive the OEM cores are to Steve's, there's no comparison.

As to not needing a tune, do a little research before deciding that. Every bike can benefit from a custom tune and even if you get a canned map from a pipe builder.

In my case, the map I got from Fullsac was a good starting point but wasn't perfect for my bike. Front cylinder was lean, rear was drowning. There was a vibration after installing the pipe/map from 1800-2800 that wasn't there before. Dyno showed why. Even if I couldn't feel something was off, unless you have it Dyno'd you wouldn't know. It's worth the $4-500 to have your bike's map dialed in.

Just my .02C.

You need to find a new shop that understands EFI tuning and how the stock system works.

So yes if you install the new head pipe ( any one) and mufflers it will NEED a tune. However when you do locate a shop that knows what they are doing you will be happy you made the choice.
