CVO Muffler Question

I have a 2015 road glide special, getting ready to put on some HD stock headers that have the cat removed(I already have installed a FP3 tuner). I have read a couple places that the CVO mufflers are a little bit more restrictive, does anybody know if that is the case. I am considering putting on a set of those to keep the sound closer to stock after putting on the headers.

Also, any suggestions on the best CVO year that I should look for.

Hi there FLTRXS15; now where to begin. You have to keep mind that MoCo put in a lot of R&D in to make an exhaust system that works spotless for the big cube CVO-engines. If my memory serves me correct your model has the 103ci mill whereas the Rushmore-CVOs are in the 110-114ci range (the 2018 CVO with a 117ci engine!).

If you really want the CVO-mufflers you should replace the core with an aftermarket like FULLSAC (since you reside in FL that shouldn't be a problem). They offer three power-cores 1.75" (quiet but still powerful low end torque), 2.0" (mid rumble) and the 2.25" (biggest and baddest...). While at it get a SE Heavy Breather or High Flow Air cleaner kit!

I personally prefer quiet so I can enjoy the music from my speakers and cruise for miles without suffering a head ache!

Thanks for the input, after doing a little bit more research probably hold off after I install that new header pipes just see what it sounds like.

I had the stock header on my 16 with stock CVO cans. Sound was great, fairly quiet. In a quest to reduce heat changed header to a fuel moto stainless coated, no cat; Sound went way way up and tone was really different, not to my liking. Changed out and installed CVO cans with 1.75 fullsac and they are still loud, to me, but tone is great and performance is great......taking that cat out really changes things up...as ^ said, those CVO cans are designed for the 110, not 103, so they aren't super restrictive..the 16 CVO cans look great. I believe most of the difference is in the end caps...good luck!!!

I run stock CVO mufflers with a Fullsac DX header. Nice sound, very quiet, enough power.

All, thanks for the replies. I should have the headers with the cats out one day next week is my friend doing them. After I get them installed and see what it sounds like and do a tune with my FP3 I'll make the decision how I want to go. All the information given by other posts here have been very helpful.

Thanks

The best sound I've heard so far has been decatted stock head pipe with American Custom bomber slip ons with their signature end caps. My buddy has this setup on his 14 StreetGlide and they sound awesome.
I have a 15RGS with rush power duals and 4inch Rinehart slipons, and I envy his sound. For $199 you can get their pipes which are stock Harley pipes with their customization. If you send in your pipes as a core you get back $75 making their pipes $125. The signature end caps are $148 for the pair. They look great they sound amazing.
