1. The two parts of the exhaust that mount up to the cylinders are smaller in diameter than the rest of the exhaust system. Are they the same as the stock system? Can I put on a full termi but leave those two pieces on from my stock system?

2. What is the full termi made system made out of? Is it titanium?

Thanks!

The rear header is reused but the front one is changed.

It is made of stainless steel.

If the header pieces were the same as the OEM, I sincerely doubt they would be included in the full system. You should replace the entire exhaust with what you have. They are made of Stainless Steel.

I'm assuming most if not all of the original full termi kits have been sold long ago. Which means if he has a replacement rear header he has to use it. It OEM piece will not fit with the newer kit.

Reason I'm asking is because I have a full system, but the front header is broken. But When I looked at my bike it looked like the headers were the same as my stock system.
So I was thinking that I might be able to use my stock headers.

But since the system is made out of stainless steel, I don't think there will be a problem cutting out the broken part and welding on a new piece of tube.

My Termi sys uses the stock rear short header, but the front was replaced. Don't understand why they weren't both replaced with the termi setup.

I'm not a huge ducati guru but i been tuning cars since I was 8 and exhaust and performace is my speciality. If you are using any part of the stock system then you have a bottle neck in your exhaust. If they open up the exhaust in the front but then use the stock rear header you COULD be losing power. Not from stock but from what you could have with the right set up. Exhaust has alot to do with sound waves. If the tubes are equal length and same diameter they will have a different wave which will thus effect the velocity of the gases exit from the engine. If you have exhaust exiting from one side of the motor faster than the other your engine cant get its full potential. I would definitely check the inside diameter of the stock rear header. If it was larger to start with and is the same as the fron then it may not be much of an issue just weight savings. But if you have 50mm rear and 70mm front (just using examples) that could really mess with the way your motor runs.

The exhaust ports are still the same size. You can't make the new exhaust any bigger at the manifold. The stock rear manifold is very short and just connects to the primary pipe. The stock front manifold however is one piece with the primary pipe. So in order to increase the size of the front primary,it was necessary to make a new manifold.

Why Stainlees Steel and not titanium like most full systems, as their can't be much weight saving?

I wasnt refering to port size i was refering to the size of the pipe. You know how some performance exhaust set ups increase tubing diameter along with changing the angles for optimum exhaust velocity. Thats all.

So basically you are saying that the rear manifold is what an inch to two inches long? that wouldnt make any difference. But the design would. now is it a 4-2-1 set up or 4-1 where all 4 pipes from each port meet at the collector?

full vs. "really full" Termi systems

My Termi sys uses the stock rear short header, but the front was replaced. Don't understand why they weren't both replaced with the termi setup.

cloudrider,

Early Full Termi kits use the stock rear header while later kits use a slightly larger diameter rear header. Per DNA, this change was done in order to better fit the exhaust system inside the fairing, and had no impact on performance. Here's a link to an earlier thread which explored this issue at great length:

My full Termi system replaced both headers.

4 into what?? The ducati only has 2 cylinders, champ.

Rear manifold is #9 on the schematic.....

for some reason I thought it was 2 on each side my bad...
