termi titanium

[daithihalton]

Hi I picked up a titanium termi end can p/n 96113203b for my 2005 999 biposta deep sump model, I know I have to get a new link pipe to get rid of the cat but looking at the end can it seems to have 2 54mm inlet holes instead of 1 small and 1 large inlet holes, does anyone know what i need to get to fit this to my bike ??

I believe the Titanium Termig end cans only came with the full 57mm system ? so you'll need all new pipes as they are a 2-1-2 configuration. And if this is the case I was warned away from the 57mm as it's to big for the Bip engine, breaths too much and upsets the compression. 54mm is as big as you should go.

Yep 54 should be max for bip.
However if you are stuck with what you have try looking if some one will make a sleeve so you can use stock can pipes or 54mm pipes.

If not I have a termi for sale where slip-on will fit

Hi daithihalton, welcome to the site!
The 57mm is fine for your deep sump 999, it's the non R 749s which don't like it.
Sounds like you need a full system in 57mm then, time to get the wallet out again.

You wernt far away and in fact if the bike had been a year or so earlier youd have been completely correct but the 999 got a better engine in 2005 taking it to , almost , the S version . That engine can run an even bigger zorst.

Thanks for the warm welcome and the info Ill have to keep searching to see if anyone now has link pipes, back to ebay so

Hi daithhalton,


There is a cheaper way of fixing this problem and I have the part you need......
The rear plate of the end can with the two inlet holes in is just pop riveted around the outside, if you drill out the pop rivets an fit the Termig plate I have available it will fit straight on to your original link pipes....

I'll take a picture and post it on here so you can see what I mean....

sounds perfect ill pm you thanks!!!!!!!

Heres the pics that I promised to post.....just so everyone can see what I was describing.....

Ok this has been bugging me for a while now,

I assume you guys are all saying that 57mm+ exhausts fitted on a 749/999 'base' model engine will affect the compression because there would be less backpressure then that of a smaller diameter system fitted...

can you back up your theory with evidence?, does anyone actually *know?* or are you just guessing and jumping on the bandwagon?

I find it hard to believe that a 57mm will have negative effects over a smaller system. Obviously I know how a exhaust sytem works and have researched a lot on gas flows etc, but on a 4 cycle engine I dont believe that this would create a loss of power.

I had a 57mm system fitted on to my 749 racebike and could deffinatley feel the increase in power on the top end of the rev range, although it seemed to lose some torque in the lower revs it strongly gained it in the higher range.

I guess it could be that the optimum system is a 54mm and that creates the ideal amount of backpressure etc etc.. but still not entirely convinced

I didn't mean this to sound rude or anything, but just highly interested to know if there is and hard evidence, or just myth...

anyone in the know let me know what you think on the subject.

regards

Hi a big thanks to XP I got the can end from him as in the pictures removed the 54mm from the titanium termi and fitted the one from the pictures, I also ordered the leo vince de-cat link pipe and ducati race air fliters (have a power commander already) to go with my system fired it up today and it sounds awesome
thanks again!!

I was told this by a dealer, backed up here. For a race bike I suppose your needs are different so it might be fine if the bike spends its life in the upper end of the revs.

Excellent, glad you got a result.

Try to get hold of a copy of the Ian Falloon Ducati Performance Handbooks, he goes into great detail on the selection of certain exhaust sizes by the factory for certain models. The topic of exhaust size and power loss is also covered briefly in the 999 Birth of a Legend book I seem to recall.

Guys who may be able to provide evidence is people like Chris from CJS racing and the husband and wife racing team that is on here. There are also a bunch of Dyno charts that guys post up here whenever they make a change to their exhaust systems,
Hope that sorts out your question.
