• 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.

Installing Two Brothers Dual Exhaust and Juice box

hello everyone i had a question. i did a search but wasnt able to find a solid answer. I just got a 6month old two brothers dual along with a juice box off ebay for $565, sounded like a good deal so i jumped on it ( let me know your opinion ). I was wondering if i needed to put the juice box on right away. i was looking to run it without the juice box for a bit but it seems that some people have issues without them and some dont. also when i do install the juice box is easy to uninstall when i need to take it to the dealer. i just had my spyder to the dealer a month ago and all the most current updates were applied ( so they said ), but will be going back from some of my 6,000 mile maint. Thanks for the help!
 
With the extra airflow you're really gonna need to add more gas to the engine.

Removing the JB is pretty easy... not sure if most bother to remove when going to the dealer or not.....

I would be curious to know from others...... any good reason to remove it when having service done>???
 
sounds good, looks like ill be putting on the juice box with the exhaust... i forgot to mention i am still running the stock air filter, will soon be adding some type of drop in filter or a race filter not exactly sure yet. yeah the only reason i was going to remove the juice box was because i am still under warranty.

some dealers will look the other way others won't.
talk to your service writer and be on his good side helps.:D
my last dealer told me keep everything in place when it's time for service but take everything off if a problem developes that require a warranty service.
 
high performance

if you enhance exhaust flow you need to match by adding air flow. you'll be running lean. jb is a must. that's why two brothers offer system as a kit.

:agree: they all go together.
more air out, more air in, more fuel = more performance.
too bad spyder needs better suspension to put it all on the pavement but if brp puts everything spyder or spyder ryders need, a lot of people will be paying for stuff they don't need also.
 
I doubt the average tech would even notice the JB is installed.

I don't see that it should cause any issues with doing a BUDDS update--- so mine is staying right where it is during service work.
 
BRP will honor all warranty work unless it is pr oven that your mods caused the failure according to the BRP tech I talked to.

:agree:
Iv'e been saying that for over a year , Starting to get some believers now, Nothing changed,engines worked that way since the internal combustion engine was invented.
 
Thanks everyone for the input.... i installed the juice box with the exhaust. All i can say is i wish i would have done this last year. The sound and power is awesome. I deff know what you mean they would have a hard time finding the juicebox... those injector plugs were a pain to install took me an hour to get the right one and about 20 min to find the left one haha.
