I don't know what the outside diameter of the exhaust pipe is on the C5.
I don't know what the outside diameter of the exhaust pipe is on the C5.
If it is the usual 1.75", then any typical 1.75" inlet-size Bullet muffler or Harley muffler will work.
You can also get copies of the old Brit mufflers in that size too, and if it is smaller, there are some size variations made to fit different size pipes too.
It's pretty wide-open in terms of selection.
You may have to make up your own mounting strut, if the bracket isn't a perfect match.
I think 1Blackwolf1 has a Dunstall copy that he's not using, and you might contact him about that.
About this change of muffler - I'm a C5 owner in the UK and would look to change to something a little bit more throaty in the future .There is plenty of choice but my only concern is that the EFI has been setup for this factory fitted silencer .
Question - When changing the silencer do you have to consider an adjustment to the EFI system or do's it automatically compensate for the change ?
Cheers

Yeah, it's good ain't it?yeah, i'm gonna have to get me an old-style torp and a fishtail for the end. that would sure as hell get me some looks. gonna be a while before i can afford a new exhaust system though...

I confirmed with my dealer that a. there's np capability to remap with this ecu and b. that the sensors should pick up the differences from switching the pipe and compensate accordingly.

Doomed1 -heh,thanksfor the offer stumpy, but the kind of fishtail i'm looking for is closer to this:
I've got one of these that I didn't use... went with the straight one instead. Nice sound, not too loud...
PM me if you're interested.

A 500cc Thumper,on a very light bike, may not reach the Ton, but you gotta Try, No?
Any info on a freer flowing air box? And it's effect on the mapping? For my personal TT course, on my 50'x100' lot. A 500cc Thumper,on a very light bike, may not reach the Ton, but you gotta Try, No? Now I'm no fuel injection guy, all my experience is with carbs and rejetting, Trial and error, and a good ear.All those lines and graphs are confusing. SO , if this EFI is set up in a very forgiving way, it would seem to me that air flow at intake would not effect mapping. Sea level too 18k almost seems sloppy. Dan.
ScooterBob, thanks for the clarification on the EFI. As I said, I know a big O about EFI. So here starts the learning process. I was thinking in terms of how a carb delivers fuel/ air to the motor. different jet sizes/ needle clip positions , etc.for various air box/exhaust mods. If the MAP can detect various altitudes, temps, baro pressures ,etc. can it also adjust itself for volume of air flow through the motor?
Dan.
Throw your pocket tuner and your drawer full of jets, needles and voodoo dolls away .... you can RIDE this bike!! Hahaha!! ;D
Dan - The MAP (manifold absolute pressure) sensor is capable of reading everything from an absolute vacuum to about fifty inches of mercury (boost!!) in the manifold. It is the programming in the processor that allows the system to USE that information. Again - the mapping is SO wide in the little UCE bikes that a fellow can leave the airbox and the silencer in the floor and it'll run just dandy ......... I've heard ....... ;)
Just remember when performing modifications to the engine that you have the potential of making it run WORSE (especially on the intake side) by not providing a large volume of NON TURBULENT air. This is vital for the MAP to "see" only pressure changes brought about by atmospheric conditions or throttle position. If turbulent air pounds the sensor (which is VERY sensitive, BTW) it'll not know what to tell the processor and the entire fuel / timing curve will be affected. This is why the airbox on the bike is big enough for a dump truck. It smooths out the airflow into the throttle body - even at wide open throttle for the best consistency of performance.

Hi..Just bought my C5, haven’t even picked it up from the dealer yet. It’s my first bike ever and I had to have it because it looks so darn good! The sales guy made some phone calls and told me the upswept exhaust was due in the end of next week. It will cost around $325. Maybe he just made all that up? But it’s what he told me today.
Is the UCE header pipe 1 3/4" diameter?
I'll be ordering a C5 Military today, and I've found a Massey Ferguson tractor muffler with a 1 3/4" inlet I think will look great with a mild upsweep...
Mike and Stumpy in Michigan... haven't decided on what to call the new one... ;D
The pipe itself is 1 3/4 but it tapers down to 1 5/8 (OD) where the muffler attaches.
Congrats on the new bike.
Anyone know where to get the upswept muffler? Nfield Gear only has the Angled Pipe Adapter. Thinking one like this guy has http://www.youtube.com/watch?v=OBfMa5o5qGk
