for the dyno dude and exhaust junkies

[johnnie27]

Greeting , i ma wishing for some info on bike exhausts

i would like to run a semi-custom system, what i am asking is this

1. if i use the termi manifold kit with the dedicated ecu, can i add this muffler (termi muffler see image)
2. i would like to run two of them actually . from a custom pipe of the factory termi manifold kit , but of-corse open to suggestions (i know there is a dude taht added a yoshi can ) just keen to see if the results are good or bad

will i lose power/ or make around the same as if i were to add the factory termi single muffler .. as i am not a mech , i have no idea! i do like the sc-project real 2-2 system but by the time i add the seimens ecu..its way expensive

for my evo sp 2010

any thoughts appriciated please

You can add any slip-on to the Termi header you want, but depending on length, volume & back pressure you achieve will determine the amount & type of power you will get, obviously the closer to the Termi dimensions you can make it, the better it will perform with the Termi ECU, with different dimensional changes, you will probably need to add a PC or smilier device to get the correct fueling.

great thanks alex, i guess the best thing to do is see a exhaust / bike dyno place and ask..

as at the end of the day i want the best bang for the back, but something custom would be nice for a point of difference

thanks for your'e input mate

The headers are the important part, equal length at 720 mm is optimal and perfect, they will evenly purge and pulse and your bike will sound like a V2 instead of a V1.75

ALL slipons etc are open perf pipes, the longer pipes tend to give a deeper boom, the shorter pipes a raspier bang, all in all if there was .25 to .5hp in that would be it on a bad day.

So fill ya boots and design something well cool that you like.... then pics !!

thanks Monstaman , i spoke with a guy that sells the R6 pipe here in oz..its around $390 bucks more to buy it here thatn in the USA (go figure i know) anyway , he said even if i use the correct ducati header and link pipes i still may make less HP than i started with...i ma not sure if he understood i was using the duc headers, as i mentioned custom a few times..i know with my car a twin turbo thing that the first 3 feet is critical (downpipe and cats), then the rest (very end) as straight thru mufflers are all fairly similar) are not as important for large gains..i have had it dyno'd with different mufflers..the results were w/in 2-3 hp ATW hp .. on a car that makes over 500hp its not a big deal..but are bikes particualry sesitive afetr the headers and link pipe? (not according to your knowledge) which is what i thought as a guess.i have to do another 600 kays to run my bike in...with this weather taht could take a while..but i am keen to make something that works and looks different and not BLOW$$ on looks , if you get my drift...as teh full termi kit outa the US is around $3k delivered ..sorry to crap on i am just keen to learn and see what experiebce others have..there is a guy on here that fitted the SC pROJECT 2-2 , but i have no idea of the HP gain they make either..

so thanks Monsterman

Another option is to get custom headers fabbed up to whatever you like.

I think 2-2 using r1 racefits fitted under the tail would be horn

Also you have PM

Any after market header system should be fine as with any can you stick on it.
You shouldnt lose any horse power, but if you want to make some modify the air box or even better ditch it all together and get some pods.
HP will come then but you may need to adjust fueling via some after market device.
Then again you have a SP so after market fueling is still on the drawing board I think.
Headers and can should be ok but then you still have to insert those o2 sensors in what ever you do.
Ducati really farked up by using siemens and dual o2 sensors in my opinion.
They have tried to keep the homagroanies in production so others cannot follow due to their siemens ecu, but people will hack it sooner or later.
Good luck.

thanks mate, i understand about the sensor thing closed loop is not all bad i am sure the tech boffins are figuring something out as we speak, as the new monster has seimens ecu and PC have a program for that...shouldn't be long

This is it in a nutshell, don't be fooled by people selling shit cos they normally have more interest in $$$ than your outcome.

I would seriously look at Zard headers from Anthony at Desmoworks, 45 mm header so 5 mm bigger than factory, equal length so even purge and pulse, includes the intermediate pipe which you could chop and fab till your heart is content.

Go mad with something custom after great headers, just make sure that you use equal to or more than 45 mm perf resonators so as you don't add restriction although if you are doing a twin system you could safely peg it back to 40 mm.
