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.

Seen these on e bay but seems too cheap. Anybody had any dealings??

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.

Seems really cheap at �299

Does seem cheap but have they have plenty of positive feedback and sell loads of cans and full systems on a daily basis. Check their feedback out.

Now have update, my cans arrived today so not bad delivery, I ordered on 3/2/09 at 20:30 and they got here today from Italy so only took 6 days. They are LeoVince X3 road legal cans with removable baffles and carbon fibre hangers. They look really smart and came with fitting instructions and all securely boxed in original packaging. Got to say at �299 including postage they are a bargain. Now just got to wait for my PC3 to arrive and the snow to melt then I can start bolting my bits on. Only rode the bike fo a couple of miles when I bought it but have now bought her Cans, PC3, K&N, DNA stage 2 and a stage 2 filter cover (courtesy of worry bro) Maybe I should have spent more time riding lol but she was a bit quiet when I took her out. These should make her sound a bit better and release a few more horses as well as shedding a few Kilo's.

Whats a PC3?? Sorry new to this bike and its mods
