• 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.

Collective Brain Storming for Header Routing.

Let me start off by saying, I do not have a Spyder to use as a reference. I would like to appeal to the Spyderlovers technical community for brainstorming ideas on how to better route the headers outside the Tupperware. If we could have some pictures of a naked Spyder it would help. Hot rodders have always been able to come up with innovative solutions to auto performance. Maybe by combining our efforts, we can devise a simple header design on paper, so to speak, that BRP would notice. Disclaimer, I'm only suggesting this as an exercise. I AM NOT jumping into the fire stuff. I am not advocating circumventing BRP's R&D. I'd like to throw some questions out for "chewing on." Please be objective!! :chat:

Could the headers be run straight down and along the bottom of the undercarriage?

Could the Cat converter be put into the Muffler and out from under the Tupperware?

I would like input from the Techies.
 
Putting the catalytic converter into the muffler would help; :lecturef_smilie: IF it's possible to do so...
We need the BRP techies to answer that question... :shocked:
Since those pipes will run basically from the front to at least the midscetion of the bike; I'm an advocate of more aggressive venting to allow for airflow around them..
But that might also create more "hot-foot" issues... :yikes:

HELP!.
 
You asked for pics, so here you go. Seems we ryde a 'naked' Spyder quite often

Hope these can provide some visual info for your chewing pleasure. We took all these pics when we removed the OEM AirBox & Resonator & replaced it with the KewlMetal Air Intake, so many of them are of the engine compartment area so some should be useful. If you need more of specific areas, just let us know, cause we have the sled stripped down pretty similar right now & can easily take more ;)

Teddy thought these diagrams might also be useful- These denote a 2011 RT-S SE5

CAT location is usually determined based on where it needs to be to maintain an efficient operating temp. Moving it further back and into the muffler unit may drop the temp too much...
 
THIS MIGHT BE A PROBLEM

It must have been the different state of tune that the old 990 engines had that allowed it to work? :dontknow:

Not sure what you mean, but if you are referring to the SeaDoos, 4-wheelers, and such, they are offroad vehicles in most states, and with that they don't have the strict emissions regulations. It's possible they didn't have a CAT on many of them.
 
Exhaust

Has anyone looked into the Ceramic coating to keep the heat inside the pipe til it get to the muffler? It would also help with te CAT Hot roder use it all the time. Is it a possability. :dontknow: jtpollock

Oh! Sorry... The 990 series engines were the ones used on the GS/RS bikes up until 2013. They were tuned for more peak horsepower, a little less torque, and were the "throttle by cable bikes." these bikes hid the cat in with the muffler
The 991 series engines were used in the RTs from the start; throttle by wire, higher compression ratio, and the powerband was moved down the rev scale about 750 rpm or so... These bikes have always had a separate cat.
 
Did the 990 series possibly run leaner? That would provide the justification to move the CAT back to the muffler housing...

Or maybe the 991 series needed a larger CAT?
 
Why don't they just heat wrap the pipes, insulate the gas tank from the factory? That would be easy to do. Ventilate the bottom panels, add a fan or two to move more air. Cheap, easy fixes IMHO. :spyder2: Tom :trike:
