Hi All,

I've just picked up my first XT660X, its a 2007 model with a power commander III and a very loud exhaust that I am trying to identify.

Can anyone identify what type of exhaust this is?
The only marking on it is the number on the nozzle, I am beginning to suspect it may be the stock mufflers cut down to make them louder.

Is anyone able to confirm or deny this?









Thanks in advance,
Russ.

Hi Russ.

I'm pretty sure the cans are Sebring judging by the end caps and the riveting. Here's an example:



Sebring exhausts only carry a crappy "heatproof sticker" so often fall off, or are removed by owners, which would explain the lack of branding. The sticker would have been where the strap is on yours, so this is probably they have gone. Of course the link pipes could by another manufacturer?

I don't think what you've got is an "off-the-shelf" setup for an XTX looking at they hangers/straps and the way it's arranged?

It's a REMUS, type FR1N. But I'm not sure if the length is original. The number is for the approval that the can is road legal in Europe. So it should not be too loud.

That was a universal type for many enduros like the Yamaha 660, Suzuki DR 350, Kawasaki KLR or several KTMs.

It could well be. Remus and Sebring are the same company!

They'll only be e-marked and "not too loud" in their original application and with baffles fitted. Just by looking at how short they are I can imagine that they're going to be fairly ear-splitting!

Awesome, thanks for the information guys.

Compared to all photos of Remus & Sebring exhausts I can find, my muflers are only half length, so I'm assuing they have been shortened by the original owner. No baffles at all.

I took the bike for my first decent ride (80km) today and by the end of it my ears were ringing!!
These mufflers will need to be replaced to pass a roadworthy inspection.

Thanks for your help!

Hi all,

Thanks for the info above, I thought I might share the results of my exhaust research.

The shortened mufflers as they were originally fitted to the bike were abnoxiously loud, and I was not keen on them for my neighbour's sake as much as my own ear drums.
So I set out to buy a stock exhaust, with the intention of running this on the bike permanently.

Picked one up from a wrecker for $220, below is a comparison of the stock mufflers vs. the ones on my bike.


I quickly discovered however that installing these would mean I needed to move the led indicators from their mounting position on the tail tidy as they were in line with the mufflers.



Begrudgingly I moved the indicators to mount them above the rear cowling and installed the stock mufflers so I could at least get a roadworthy certificate for the bike.


Unhappy with this result I set about improving the shortened mufflers. First step was to have a custom exhaust fabricator install some baffles which set me back $100 cash.
Next I needed to make them look like they belonged on the bike. After purchasing some spray paint and carbon fibre vinyl I set to work, here are the results.

Final product





Overall I'm pretty happy with the results, I was worried about heat on the vinyl but after an 80km ride last weekend both mufflers were cool enough to rest my hands on without melting my skin off, so no issues with the vinyl either.
With the baffles they also sound pretty sweet, quiet enough at idle but good bark under load...
