I am sure this has been talked about here several time. I need suggestions and opinions. I have a close riding friend who has owned several HD's in the past and is a current owner. He recently bought a 2016 SG CVO. He stated it didn't seem to have the power that it should so he did some checking around and came up with.........removing the catalytic converter (from a prior take off, keep original for future ?) and had HD tuned, he is also running Rinehart 4" slip-ons. He now states all done opened it up and runs like it should. He also stated he should have went with the Vance and Hines fuelpak fp3 instead of the HD



I have the stock 2014 Ultra limited with Rinehart 4" slip-ons and thought I would do the same. I just ordered the header from WildHogPipes with the catalytic converter removed (special going on right now $100 shipped) also going to get a Vance and Hines fuelpak fp3 66005 and a high flow breather.


So now I need suggestions, opinions, pro's and con's, Should I or shouldn't I.

 

I have a 2015 Ultra Classic and I went with Vance & Hines Power Duals, Monster Rounds, FP3, and SE AC. I'm very happy with this setup. The FP3 is very easy to use and works well with a stage 1. I did a Rush System with a Power Commander on my previous Ultra and was very happy with that setup too. I think all of the major brands do a good job with R&D and it's just a matter of which one strikes your fancy at the time your ready to buy. Good Luck.....

 

Just the exhaust change, should make it run like a different bike. It did on mine,

 

Oh no, the California Air Resources Board is reading this thread.

 

The catalytic converter is restrictive on the 16 and earlier touring bikes. I run Fullsac head pipe, which fit under factory heat shield on my 13 CVO Road King, and ran the same on the 15 CVO Road Glide I just traded. Getting rid of the cat and a good tune is worth a several HP and Torque.

The new 17 catalytic converters are very restrictive, to the point a set of slip on hardly gives any more sound. I good headpipe with no cat will be worth a whole lot of HP.

Bad thing is 17 on HD is going to try to void warranty if you change the head pipe and tune.

 

Very possible if HD just did a tune it was tuned with the EPA in mind.

 

So far no negative results. That's a good thing.


I have always liked California. But me and its politics do not get along!

 

Keep in mind, when running a decatted or aftermarket header your Rineharts will be much louder. Also I would consider a high flow air cleaner (breather) that will allow you run external breather system. The V&H V02 and DK Custom sell this type of breather.

 

I have a 2017 Street Glide, 107 stage 2 torque cam, it has the cat and it's the fastest Harley I've ever driven, and that includes the 110"S models. I don't think a catylitic converter is that much off a factor when building horsepower. Look at the Corvettes and Vipers, both have cats and both rip.

 

The H-D cat is a very high flow and just removing it does almost nothing to performance except in the mind of the rider.
