Vandemon cans and headers.

[Nashvegas]

So guessing the exhaust has to be removed and the sensor(s) is towards the bottom of the header?

Top. Right after the header clamp.

I messaged Vandemon today asking about compatibility with their headers and mufflers and they said that Euro 5 2024 models have two O2 sensors instead of one sensor for earlier models and it’s not compatible yet with two O2 sensor models. They also said that US models don’t always adopt Euro 5 specs and mine could be compatible if I just have one O2 sensor.

So my question is how do I check? Is it VIN based or something a dealership could tell me or does it require a physical inspection of some kind?

My 2024 Rocket (U.S. model) only has the single O2 sensor. Not sure about 2025 models, but if they have a second O2 sensor it would have to be after the catalytic converter has done its thing, so either on one of the outlets, or on the cat box plugged into the outlet chamber.

If you remove the cat box and there's only one wire (connected to the inlet pipe, as shown in Nashvegas' pic), then you only have one sensor.

Thanks for the feedback and the picture helped a lot. It looks like I have just the one as shown in Nashvegas’ pic unless there is another tucked away somewhere else but after looking all around carefully I sure dont see anthing. I might just call the dealership I got it from too just out of curiosity if they would know or not, doesn’t hurt.

Vandemon rear exhaust on, the Vandemon Titanium headers should be here by 9/16 and I will install them. I have a BT Moto full exhaust tune with DNK air filter. I will post how it goes once I have it installed and done. So far with just the air filter, rear non-evalve exhaust and BT tune on it runs strong, has a little decel pop on occasion, once I get the titanium headers on I will update!

Can’t wait to see it and hear back on the results!

I'm going to fit the Vandemon decat can to my GT (the open non-switchable one) and I'm thinking about adding the titanium headers as well. I really like the look of the stock headers but Vandemon say they're quite restrictive.

I'll be having a full custom remap afterwards so might as well go the whole way with the exhaust. Anyone fitted the full system and do Vandemon's performance claims add up?

I'm thinking of the doing the same (non-switchable) I have been in contact with Vandemon but as of today are out of stock of the non switchable systems, should (?) start re-production in September. I have also been in contact with Speedycom who are the UK importers based in Derbyshire, price is more but no import duties/VAT to pay (they also do tunning etc), I await any feedback from peeps if they have the same system fitted.
The one or two sensors question...does this only apply if you are having the headers fitted as well ?

Aren't the sensor/s in the collector section of the end can? I may be wrong but I don't think there are any sensors in the headers.

I'll be getting mine remapped at BHPUK at Burnley. May be worth asking them about O2 issues. They've mapped a few of them now both stock and with aftermarket pipes.

Pic of the Ixil collector. I'm sure the Vandemon is the same.

Yes, mine has just the one sensor as pointed out in a previous post, I did call my dealer who confirmed mine has only one, late 23 model I think (?) the new Storm models have two

Here it is, finally got it all done, went on vacation and then got the flu. I will post the entire exhaust shortly.
