• 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.

Catalytic Converter Bypass

I removed mine [08] The caveman way ;Reamed it out with a long Bit on a extension, Not recommended for the weak of heart.:D No other modification needed or done. Total cost Zero, But a miscalculation would have meant a new muffler:gaah:
 
So you're saying even running the stock exhaust and bypassing the CC it would be considerably louder?

Firefly,
I don't know the sound level with the stock muffler, I build the kit to fit my after market pipes.
It will sound more like a RS with the stock muffler removed and replaced with aftermarket pipe like the TB Dual.
You also can add a silencer or baffle into the pipe to quiet down a notch.
 
Maybe I'll just wait for your kit. :) What's your target date for hitting the market? I hadn't considered changing the muffler. I kind of like the looks of the stock muffler. It goes well with the RT style.

If I do go to have one built, it will be during the winter when the Spyder will be garaged, so if someone else hit the market with one, I'm all for it.

DR Buck,
I'm still in the testing phase, wanna make sure everything is well before putting it on the market.
The kit i have on mine sounds just like an RS with one of my pipes on it.
So far i can report, the range on my last fillup was 185 miles with one bar to spare. Light didnt came on yet.
That was cruising through the mountains, about 40 miles on the interstate and city driving.
I'll be at Lamonts BBQ and i will have the kit on mine, so if you're able to make it there you can see for your self.
 
Forgive the ignorance, I thought the cat was IN the muffler in the first portion after the 90. Isn't the muffler the same for RS/RT? I thought ecu adaptation was a wives tale promoted by a hindle break in procedure? Learning here guys, don't flame me.

Oh and the RS has a 80db EPA stamp on the inner portion by bike frame. My HMF is 95 db at idle, over 105 at rev.

The mufflers are different. The RS has the cat inside the muffler. The RT has a separate cat.

Cat removal

A local muffler shop removed my cat and custom made a "Y" insert. The total cost $129. Just pulled a trailer for 868 miles and averaged 32 miles per gallon. Passenger was very happy at the lack of heat burning her feet. No tune up required. This is one of the best, if not best, change made to the spyder
 
:chat:. Survey says. for few more dollars, should be able to guarantee "No Popping". IMHO, anytime to allow the flow of hot-air to accumulate in any restrictive manner...aka..2into1, you will have heat accumulation. I didnot see a photo, in the link to the site. I'm sure that the piping is created to decrease the restrictive flow. Surely would like to see a photo.:shocked:.

Cats are made to create substantial heat in order to better oxidize the exhaust gasses. The closer the cat is to the cylinder, the better it will function. Difficult to set up on a motorcycle and it's probably why ours are so large because of where it's mounted. Had they wrapped the exhaust, it probably could have been a smaller unit and still passed Leftyfornia requirements. The extra gas burned with the increased weight and restriction negates a good portion of the cats environmental benefit in our case. The replacement needs to be nothing more than a Y-pipe to connect the 2 cylinder exhaust pipes to the existing muffler. Surprisingly, there actually is platinum in most cat converters and sometimes even gold. Not sure why they priced it so high. I was really wanting this and jumped right over to their site to order it figuring it would be two to three hundred bucks. Guess it's a small market and you have to recover your R&D. Hopefully as the number of RTs increase and someone else jumps on the bandwagon, the price will decrease.
