There were many reasons for the change of the site software, the biggest was security. The age of the old software also meant no server updates for certain programs. There are many benefits to the new software, one of the biggest is the mobile functionality. Ill fix up some stuff in the coming days, we'll also try to get some of the old addons back or the data imported back into the site like the garage. To create a thread or to reply with a post is basically the same as it was in the prior software. The default style of the site is light colored, but i temporarily added a darker colored style, to change you can find a link at the bottom of the site.

Can you add a tip to the exhaust that would aim it down or away?

I see that you have a mud flap on your rear fender. I get the same thing with a 2012 and a 622 trailer. For me it is somewhat related to having the two mud flaps. The one that’s installed on the trailer hitch together with the other one we put on the rear fender appear to dam up air flow. Pull the trailer and the exhaust seems to get pushed back or sucked back to the rider. We remove the fender mud flap, keep on the hitch mud flap, and things improve. So, try removing that inner mud flap you have and see how it goes...or the other way around. Yes, wind direction also plays a roll. Tips would be the ideal fix, I think, but I’ve never come across ones small enough for the holes in the muffler.

Several others have the same complaint about fumes. Not sure about a cure yet. Even on the 622 trailers

I know I tried moving the side air deflectors and open my windshield vent which did help..
Baker Built air wings may help you for this issue??

Our Spyder RT's create a lot of turbulence behind them, turbulence that in dry weather lifts up & coats the back of the rear trunk & panniers with dust and in wet weather lifts road spray from the tires & rain that's been diverted around the Spyder such that it covers the back of the Spyder and drenches the back of the pillion passenger, and for some, it also sucks up the exhaust fumes released into that area - make that 'for many' when you are towing a trailer, as you've already found, DMartin. :sour:
Changing the mudflaps &/or angling the muffler outlets down & away can help a little, and may well be a part of the 'complete solution' for some, but I found the best 'fix' for this 'suck the fumes & dust/rain/spray up' problem to be quite simple - I fitted a Spyder RT Rivco Adjustable Luggage Rack onto the trunk lid! The rack acts like a 'whale tail' spoiler & smooths out the trailing vortices & other turbulence that creates this unruly low pressure area behind the Spyder, so it no longer creates the circumstances that cover the back of the bike with dust & road grime in the dry, no longer drenches the back of the pillion in the wet, and no longer sucks up exhaust fumes even when towing. :clap: Even in its un-laden 'open lattice' condition without anything on it, the rack works fairly well as a spoiler, altho I found it worked even better when I had something on the rack, so that led to me fitting a piece of light ply simply to cover the flat deck of the empty rack. A couple of minutes with a sheet of 1/8th" thick plywood, a sharp knife/box cutter, and a lick or three of clear poly paint to seal it was pretty much all it took!
These days, the 'deck cover' lives on the empty rack held down by a few screws, except when I put something on the rack, when it comes off in seconds & slips vertically into the frunk, taking up very little room - and regardless of if we are towing or not, both my pillion & I no longer get gassed by exhaust fumes or covered with the dust or spray from behind that's sucked up in the un-regulated trailing vortices & low pressure area created behind the RT by the trunk & panniers! :thumbup:
The rack comes in chrome or black powder coat, and I believe that someone has made a different version out of flat plate (without the holes or adjustable features) that is intended purely as a 'whale tail spoiler', but haven't been able to find the link.

Yes, found it on your value accessories link, nothing on Rivco. Pretty neat looking rack, pricey though. If it fixes the problem, then probably well worth it, also serves as more luggage space.

Please report back on the success/failure of it. (not that I am in any way saying that Peter Aawen's claim is false) I am the "friend" that Dmartin was talking about in the original post. I have tried the removing mud flaps, air wings and my oversized windshield. Nothing worked. I really do not want a luggage rack on the back of my bike. Tomorrow I will be measuring up and getting some pipe extensions for the muffler. And yes I will post my results. I will get the luggage rack as an absolute last resort, but it is a permanent change to the bike, weather it works or not, as you have to drill holes for it. So, please let us know how it works for you.

:congrats: on the RT and Trailer combo. :yes:
I cannot help with the exhaust problem...but the advice looks go so far.

I have not thought about that. I believe the issue is that the exhaust from the bike is pointed towards the tire, and is not far enough to the rear of the bike. The exhaust get caught up in the back draft of the bike, and with the trailer on, it cannot escape before getting sucked up and over the rear of the bike (much like the water that drench's the passenger)
I have been experimenting with extending the 2 exhaust pipes after they leave the muffler. So far it seems to be working. We have done a couple small trips around town but I was not going to report on this till after we our trip to the Pac NW spyder rally in a couple weeks when we can really take it on the road.

There is a vendor that offers an extension but they can not be named on this site.

I have tried windshield in all positions, as well as a larger windshield (7 jurock) I've taken the mud flaps off, add a larger one, removed the air wings on the front side (this did help marginally) I created a shield to try to divert the exhaust to the outside of the bike (made the situation WAY worse). But, thank-you for suggestions, I am open to any that may help this situation. I like my wife, and want to keep her around for awhile longer.
