Hello,

I have a 2007 model XTR with 31000 km on the clock.
I have been thinking about getting a 2 in 1 system, i already have 2 leovince x3 silencers on it right now.

Is it possible to only get the headpipes ( http://www.off-the-road.de/en/XT-660...em-XT-660.html) and add one of my Leo x3 silencers on this?

And if so are there cheaper 2 in 1 headpipes available on the market?

Thanks in advance, and greetings from holland.

NA.

You cannot do this because you practically you want to "squeeze" the 660 cm3 flow in a 330 cm3 pipe. Simple. The Leo's pipes are engineered for 2in2 not ment for 2in1 system. You will effectively "suffocate" the bike.
If you want 2 in 1 you have to buy full system or find a pipe from 660 or higher capacity bike.
This is to explain it simply
