Race cans and chips...?

[GI Jnr]

I've just picked up a new 999 and was planning on getting a Termi system fitted.

For those of you interested in italian sports cars, you'll know all about Tubi-Style exhausts.

Well... because of my addiction for having these systems on my cars, I've been offered the first system in the country! Free of charge!!!!

The full details are a bit vague, but the top system is apparently made from a material called "inkenel" (don't actually have a clue if this is remotely right, I was told over a rubbish phone line...)

Now, back to my original question. When fitting new systems, is it essential to have a chip fitted? I appreciate that it may be highly recommended to get the best from the bike, but does it have a detrimental effect if you don't?

TBH, it's only because at the moment, I genuinely think I wouldn't notice the difference in performance as my riding skills aren't quite on par with my skills.

Also, they offer two sizes of systems: 40 something mill and 50 something... (57?) Is this purely the bore of the cans and therefore, the amount of noise? If this is the case, bring on the big bore!

Sorry for the rant. any advice would be very

With free-er flowing exhaust you will move more gases through the engine. Unless it is 'chipped' you will simply move more air with the same amount of fuel - bike will run lean, lose power and run hot. Worst case scenario - if you really cane it you could end up with engine damage. So get the fuelling sorted! (no point in a race 'zorst if it makes it slower)

Bigger pipe size will move even more air so will give more power (when chipped) also more noise.

Be careful with the bigger sizes (57mm etc) as this sometimes means the pipe work is nearer to the fairings and other parts - can mean melted plastics etc.

btw, the exhaust on the Macca F1 is made from inconel (sp??)

I read an article about Akrapovic exhausts in MCN a few weeks back, I think they said that 'Inconel' was less brittle, (or something), than Titanium and so can be used thinner meaning it is even lighter than Ti.

Thanks for the replies!

I was told that Inconel was the new top material...

Now, my next dilemna is this then: Which chip do I fit? Are there standard ones that are programmable? I'd assume a rolling road session would be recommended to get the chip remapped for top performance, like you would a car.

Thanks again for any help.

It's not just a case of 'putting a chip in' on a bike.

Take it and get it dyno'd properly after you've had the zorst fitted. That way they can set it up for you and it will be right from the moment you've had it fitted.

So do I understand the Tubi are now making bike zorsts

The 999 (and 749) are really growing on me but I really don't like the new exhaust

Be sure to post some piccies as soon as you have them

(I have 56mm and a chip and it sounds the bollox )

[catso]

Actually I think a new 'chip' for the 'Testastretta' engines 998/999/749 is actually more than just an Eprom as per the 916/996/748.

I'm sure it involves more expense and time (Dyno?) to set up than the old engine but you will not be disapointed as there is more power to be had than the older 'tractor' engines

Remus do a Twin Pipe exhaust for the 999, for the more traditional look

[GI Jnr]

So, just to make sure I have this right:

-I get the Tubi 999 exhaust.
-I take it to a specialist for a dyno/set up session.
-They fit the exhuast, and fit a "blank" chip in the bike.
-Then proceed to set up the bike with the new exhaust fitted!

I was just worried I'd need a special "Tubi only" chip...

God! I'm a genius!

I can't wait to hear one, especially compared with termis.

My MV wasnt running properly when I bought it, the previous owner had just fitted the sports pipes without a chip. I had a power commander fitted & the power was much smoother & removed flat spots.

If you have any probs give casoli a call www.casoli.co.uk/

Catso,

Thanks for that, I might just have to get one

Testastretta engine requires a unit upgrade and not a EPROM chip change like the old 748/996 engines. I believe that the likes of moto rapido or sigma provide mappable units at a cost of around £500. Expensive in comparison to the old Ultimap chip at around £140. Ducati Performance do off the shelf upgrades but are again generic maps and are not real time mappable via a rolling road session.

So what, just look at the bloody thing



How can you consider going to the dark side

[veetwin]

I assume that you refer to the possible looming Jap Purchase?

On another note, last weekend found my gearing now allows third gear to be selected whilst the front wheel is aloft and a private purpose built roundabout allows some titanium slider grinding. Got to book Donington Park SOON!

Yes those pipes look great, all it needs now is a single-sided swingarm, Fox-eye headlights and a 'sharper' fairing

Nah that would make it look to old like one of those 916 things

Though they do need to

BRING BACK THE SINGLE SIDED SWINGARM!!

[GI Jnr]

Sorry to ask a possibly stupid question, but if I just fit the backbox, will I need to have the bike chipped/dynoed...?

To be honest, at this stage I just want the noise...!

If this is the case, I can just fit the rest of the system and get it set up when I'm ready for the next stage.

To do it right it will need 'chipping' for any mod, it would then need setting up again for the next mod - so you'll be doing it twice.

You could not bother chipping and it will probably not cause a major problem (if you're not caning it too much) but what's the point? I'd do it properly if I were you.

[GI Jnr]

Decision done then, thanks for all of the advice.

I'll get the system, finishing running in the bike and get maybe another 500 or so miles on it to bed it in properly and get the whole system fitted and the bike chipped and set up.

It's not as if it sounds bad as standard anyways...

Thanks again

Tuan
