Guys,

Is there any real bennefits (besides the sound and the beauty) in installing a X3 LeoVince pipe in a '06 XT660R ? I'm asking because they are really expensive down here in Brazil (around US$ 1.200, a set) and I would like to evaluate if it�s worth the investment.
I've already ordered a K&N filter, a Power Command III and will remove the snorkel. My goal is to gain some additional HP and torque and install also a 16 front sprocket, to have a more "confortable" bike in the highways.

Thanks a lot in advance !

(sorry for the bad english)

If it's HP you are after you need to order a stage 2 DNA Filter as well, these motors need to breath & are restricted by the intake system.

(Quote) DNA stage 2 filter only, standard main filter = 3.1HP. (Best gain in HP & torque for your money.)

Most of the pipes offer around a 2 HP gain, with a big weight saving. So don't just look at the HP gain but also the weight reduction, the HP/weight ratio is better with a after market pipe.

Thanks for the very quick answer Kev.
Do you think that even with the baffle in (FIM option) this pipe will perform better than the stock one ? (considering only the K&N filter and the snorkel removal )

Thanks again !

Marc�o

Yes I do think it will perform better than a standard system.

Will let you know when mine arrive as I have just bought a set (3/2/09) also bought a PC3, DNA stage 2 and K&N Stage 1, now just have snorkel to remove and goodies to fit.
I have a 2006 model XTX on an 07 plate, thoughtI was buying an 07 bike and didn't bother to check
Maybe then have to book some dyno time, but will start with some maps from here first.

get them get them get them.
i fitted them to my bike and i am more than happy.
for sure there was a power gain. also have done all the filters and snorkel thing.
