Exhaust

SS1913 · Dec 9, 2023

I just purchased a new ADV Northstar 2 seat and am curious about exhaust options. All I currently see are Bikeman and Aftermarket Assassins. I have used them both on other units and leaning toward the Bikeman, but wanted to see if any other options are available or if anyone currently has one of these.

Thanks

I haven't had Bikeman or Aftermarket Assassins. On my Ranger NS, I ended up going to GGB, primarily because of the size, shape and placement of the muffler. It made it a whole lot easier servicing the transmission. The stock muffler was right in the way, and required using a long extension to remove and install the plug. It was always a pain to clean up the fluid afterwards. The GGB took care of that issue.

I contacted GGB back a few months ago and they told me they were waiting to get their hands on an Xpedition to do the R&D for a muffler. I'm waiting on them to release one. The Ranger muffler had a lot nicer tone than stock and wasn't really any louder.

I spoke to HMF this week and they told me they are planning for R&D in January on a Twin Loop that should quite it down a bit. Told them id be first in line.. lol

Ended up with Bikeman. It is deeper than stock and looks good.

Nice, how much louder is it?

SS1913 · Dec 17, 2023

Not a ton its a deeper sound.

How about a video of the muffler sound?

I wound up ordering from HMF Racing and went with their single muffler. Ordered it blacked out and quiet vs. loud. I'm not sure, but think it's maybe the same or slightly louder than stock. However the tone is much lower and more throaty...a much better sound, IMO. They claim it offers a couple more HP, but I can't really tell. I've got a Gilomen tune and performance clutch kit. I took it out and never did really run it all the way out. But it still got up to about 77mph with 32" Carnivores on it. I'll never need any top end like that riding, but the torque is nice. Gets you there quickly.
Here is a YouTube they did showing the sound comparisons for each of their offerings. I opted for the Titan-QS slip-on. I also opted for their blacked-out version with a ceramic coating over the stainless.

The thing that concerns me about the stock muffler is it’s a cat. Sure hp is a plus but heat buildup I can do without. I like a nice looking exhaust too. For double the cost how much is worth it? I found that RPM powersports has a SS that’s only $399. looks and sounds decent. Also offers the same hp gains as HMF and others. Going to give it a try anyway.

Installed my RPM muffler today. Sounds about the same. Looks great! Might feel a little more responsive in the throttle. Expecting less heat with no cat to deal with. Shipping was very fast and packing was great

I ended up going to the HMF twin loop system. It is a little quieter than stock and looks nice

Does anyone know if the HMF twin loop will fit with an HD rear bumper. It looks close.

SS1913 · Jul 10, 2024

I have an AJK rear bumper, and it fits

Can you hear the reduction in sound? The listing for db reduction from HMF (1-3) seems negligible. That said, the 4-5db difference I have experienced in sound proofing is night and day through the whole RPM range. So much better than stock...

I swapped it from the Bikeman, so yes! I had done all of the sound deadening as well the roof, floor & doors and it has all helped

I have the Polaris HD rear bumper and I don't see any reason that it would interfere with the HMF twin loop muffler. The bumper sits out far enough it shouldn't be an issue.

I have the Bikeman available.

I was going to purchase the HMF aftermarket exhaust but instead drilled out the CAT in the OEM unit. I'm so glad I did this runs so much cooler, OEM heat shield, and not one DB loader. This gives a straight through exhaust with many baffles and cost me nothing. Now I can spend the $1K on other accessories.
