I did a search to see if anyone was running the Remus exhaust over here but didn't find much. They are getting popular in the US and are the one's I want to get. I love the look but had one concern I was trying to get solved. The way I understand it, the factory muffler and I would assume the Termi's are designed internally to give the exhaust system the effect of having a crossover or equal length type set up. After installing the Remus mufflers you would loose this and have two different length pipes. How will this effect the bike or the difference between cylinders? Is it most likely something you would never feel the difference on a street bike? Wonder how it would tune and if it would create difficulties or effect the mixture of each cylinder?? I haven't heard anything negative from the guys running this system so can't be too bad...

Here's a photo just to look at. Very retro looking and keeps alot of the last generation appearance.

Nope, don't look right to me. As for the teckie bits I'm sure Shazaam will be along soon to give us the gen.

I was considering these because I kinda like the look but the Termi systems seem to be extremely difficult and expensive to get. I'll admit I have not done alot of research or shopping around but it seems like there is some debate over systems available to even fit the '05's. Supposedly older pipes will not fit newer ones or something to that effect. I can get this Remus system for around $1100 US new.

But it will make your new bike look antiquated,if you like the vintage look go for it.Personally i think it ruins the overall flow of the design.

Sorry there not for me you can't beat the sound of the Termi's

On the Tec. Side: I think you will find that the chip needs to be changed or remapped. Not sure though

Right, here goes...

If the Remus cans are just a slip on box with no pipework, then you'll keep the assymetric system. The header pipes are the originals, with different lengths, and the front cylinder pipe has a varying bore to mimic the straight bore of the rear cylinder (thin at the front, wider at the back).

The downside to this is that you'll have the rear cylinder running straight through with no cat, but the front cylinder will still be running through a cat as it's in the original header pipe. For the rear cylinder, the cat is in the original exhaust box which you would have replaced with the Remus box.

From what I have read, the cat in the header pipe is quite small and so you shouldn't really have a problem with fuelling etc if the bike is set up properly at a dealer. You could always buy a straight through pipe from Ducati, which would have no cat but retain the varying bore of the assymetric system. This pipe is used in the Termi kits.

If you like the look, then I would buy the Remus cans and a straight through pipe. You should be able to set the standard ECU up to fuel correctly and/or you could add a PCIII Power Commander and some dyno time.

Twinfan, thanks for the great advice. I knew that about the cat in the foward pipe but your description of the pipes answered alot of questions. The Remus system DOES come with a new, straight through front pipe to get rid of the cat.

As for the Termi system...what are the options? Is the only system they have for my bike the 54mm full 2-1-2 system? I know that's probably the best way to go but not for my check book. Does Termi have a system for this bike that has just the new can and a replacement pipe for the front cyl?

My only other concern is going with the 54mm full system may steal some low end power. I don't have any major engine upgrade plans so don't want to give up any down low.

Thanks guys for all your opinions on the Remus system as I am starting to agree with you the more I look at my bike

Ducati sell a slip-on (assymetric) Termi system for your bike. It's in the 2005 performance catalogue. You will need the '05 749S specific kit for the right combination of front pipe (to match the newer style swingarm) and the correct fuelling ECU. This is the cheapest Termi option available and gives you a set of air filters, a new ECU, the Termi silencer with carbon heatshield and a new cat-free front pipe. I have this kit on my '04 749S.

Your only other option is a 54mm full 2-1-2 system, which will cost roughly 60% more than the assymetric system. If you're just after a bit of noise, and the looks, then I wouldn't bother with a full exhaust. I believe it's recommended to also get a PCIII with a full system to really get the fuelling spot on and get the most gains.

OK, did some shopping around the past couple of days and nothing is available here in the US right now to fit the '05. I talked to two of our most reputable dealers (Section8, and Ducati Seattle) and they both said the same thing...the only one they are getting in is the full 54mm 2-1-2 system and only in steel. No idea if or when they will have a titanium set up in. They both have placed a bunch of orders and still waiting on arrival. Said it shouldn't be to much longer though. This will also come with the ECU and filters and I can get it for $1950 US.

Did you not go with the full system just because of cost?? Just curious. I didn't want to get a full system if it would rob some low end power with a stock engine but I've heard the 54mm is not like the 57mm and actually works pretty great with the new S motor.

What about the Leo Vinci system? and get a PCIII and some dyno time?
