Welp...no such luck. Gerry said to call back later in the year to check to see if they have anything used. Seems they have used TT250 exhaust but no RX3. Hopefully if they ever have a big parts sale,...

Well, I figured I'd bite the bullet and order a muffler from CSC for the listed 199.95. Sometimes it just doesn't work out when you experiment on mechanical stuff, I get it. So I log in to CSC this...

Long overdue update:
It's official. After a number of miles and months, I've found, at least on my RX3, that changing the exhaust to a more free flowing unit and eliminating the cat, makes no...

As compared to many bikes I've had, the RX3 exhaust exit isn't very far behind the riders head, then add being trapped between the bike and the bag. I think this could contribute to the stock exhaust...

Litmus test possibly coming up this Sunday. My brother is bringing up his bone-stock RX3. He has yet to even wash off the original Oregon dirt.
I'm curious to see if there's any real difference in...

That's a possibility but it's not a sucking sound, definitely has the pop and rhythm of the exhaust note. I'm wondering if it's echoing more because of the sound being trapped between the empty bag...

Update:
I've been messing with the baffle more. As pictured above, I ran the row of holes to the end, on all three rows. I played with the spark block moving it into different spots. The best it ran, with...

Thanks! With the injection, who knows if adjusting the backpressure will work as well as on a carb bike but it's worth a try. I figure the less backed up exhaust gasses (faster scavenging) will lean...

Baffle Tuning
Ok...so I was thinking today....there's no reason not to get full tuning ability out of this baffle setup. Like with a Super Trapp, you install and remove plates to adjust backpressure for tuning...

Performance and Sound
Sound: It sounds about the same at idle. Maybe a tad more aggressive.
