why a catalyst in only one link pipe?

chillo · 08-Feb-2005, 16:10

A friend noticed on my 999r that the race kit is one link pipe with back box, the link link pipe has no catalyst and replaces the standard one which does have one.

He asked that why isnt there one on each pipe.

Now that sounds like a good question!

Its got me wondering, but surely wont this upset things like the gas back pressure balance and a whole load of other things etc if there is a catalyst on just one pipe(cylinder)

anyone know or got an answer?

There is a cat in the long pipe from the front cylinder , there is also a cat inside the standard silencer box just where the short pipe enters it

nope , the cat for the short pipe from the rear cylinder is in the inlet to the standard silencer

Nope. One cat in the box for the rear cylinder, and one in the long link pipe for the front cylinder. That's why the asymmetric system gives you a box, a link pipe and an ECU

Its all an expensive no gain option. Get a balanced system, you know it makes sense!!

i was going to put a balanced system on, i had ordered a 57mm corse ti termi system but after seeing what ducati have done with regards to marketing bikes specifically shafting 999r owners i cancelled.

I know we have always paid for having the latest/greatest etc but i think for 05MY they really are taking the p***
Seems to me like ducati have lost the plot a bit and feel reluctant to throw good money after bad. Still seriously looking at a 'sedici but have been put off a bit by it all. sorry, thinking of buying a 911 instead!

rant over!:P

Got a pc3 which will be going on soon though

ps.

back on topic, thanks for the answers, i'd forgot about the cat in the standard back box, thats why its so fookin heavy

shafted 999r owner or not, and i do agree with you, you know with ducati bits you only really rent them! buy now, sell when used etc.....
