Hi Y'all,

I'm thinking of getting a 2 into 1 system for my 750 ('00). 

What do you think? worth it?
any trouble known after the install? (I guess this question directly to those installed on their)
And which sources do you think I can get it from?  I tried ebay but no luck.

Thank you for any comment.

Good day.

where would you get one?  I didn't know any were still available...  (inform me please!)


I think they are neat.

Start here:

MTS 620 Stainless Header Pipe for Mid Pipe - #71320MI

Add 45 degree bend in 1.875 ID stainless.

Add silencer of choice in 2 ID.

Add hangers.

Done.

I assume that dual-side swingers have the clearance necessary for the weird bend in MS headers... and that DSS monsters have very similar holes to the DSS MS.

Won't work for an M900 without chop and weld.   Ferracci used to make one just for the 900, which I'd love to get my hands on.  

too true.  I was referring to the small case motors like the OP has.

I'd like to figure out if its possible to use an S2R midpipe (800 or 1000) to accomplish the single side exit on the M900, and the commercial 2-into-1 systems available for those bikes, or simply y-pipe it together and so forth.

I want to say the DS motors have different header diameters than the other 2V engines.  

I'll tell you what, after I finish my exhaust I'll give you my udder to play with for sizing (wow, that sounds so wrong!) if you want. 

It's beat up enough that it is totally not worth selling.

 :o

hey mergatroyd you got a PM...

I just installed a Ducati Performance 2-1 system on 98' M900.
I got the system from the Netherlands, new old stock.
The pipe diameter is 2" or 50mm I think!!!?
The bike now has less back pressure...I am sure it was not a performance enhancing mod. But, in my opinion look pretty neat!
Getting a can that liked on it was a challenge!!

can you post up a link?

Is it a high mount system?  Also, do you know if they have another?

Daniele moto still has the 1000 cc sil 2 in1 system in there programm
https://shop.daniele-moto.de/artikelliste.aspx?sd=1_3
Maybe they can get a 900 cc version
Very good place to buy stuff from

I got mine from

Ducatiparts-online.com

Above is the system...it is comprised on 5 pcs...fitted by slip joints

what's the part number or the link to the exact part?

I can't find it...am i missing something?

Ducati Performance # 96002899 C

I guess they don't have it anymore.

Very doubtful, I got this one Micah , the owner said it was new old stock.
There are couple places in Italy that have the 2-1, header system.
But w they were quite expensive!
Do a search on here... Think those threads will come up.
Probably the best chance is to continually search out eBay US & UK.

Ehh?

That looks good....and you could use the stock mounts etc.
I had to have a custom piece welded midpipe.

There is a thread here on DMF re...a stcok header converted 2-1 and he had disastrous results...flames etc!!

But the results from the other forum very promising [thumbsup]

my general comment is that if they worked better there'd be more of them.

i hadn't seen the end of that other thread before.  interesting result, better than i thought it would be for the constant diameter pipe.  although the first question is "was it tuned before?"  it might have made more power before if it was tuned as well as it was after.  but, might have to try it in the spare time i don't have.  something to try on minnie after the fcr go on.  and the danmoto get tested.

given the 600, 750 and 900m all have the same size header, and that bike was a 750 cam and valve 900 motor, maybe it'd work fine on a smaller engined bike.  i have run sort of 2-2 on a 900 and hurt the power, but it was sized maybe a touch smaller.

a local guy who emails me fitted silmotor spag headers to his 900 and says it helped all over, including bottom end.

but many of these are made for weight saving or cosmetic reasons, to which i always say go for it.

the 2-2 one is interesting.  it should really hurt a 4v motor, maybe it's the diameter of the headers that helps, if you see those photos it has the normal sized pipes from headers to mufflers, with two big bends for the high mounts.

there's a guy who emails me in the uk who runs 900cc f1/tt1 racers and he says the 2-1 which was always the fashion for the f1/tt1/tt2 costs power compared to a modern style 2-1-2.  i've read that ferracci went to 2-1-2 for his 750 sport racer for "midrange reasons".  but it always depends on how good the previous version was.  if it was crap then anything mght be better sort of thing.
