Ok guys, here are the Pre-liminary numbers I got from Randy at LTE. I hope this does not come back to bite me ...

*** DS 650 Dual pipe over stock ***

5-7 hp gain
Most gain in the Mid RPM Range
96 DB (by Oregon Standards)
Lighter than stock

From my understanding of how the pipes are rounted, it seems as though you'll be able to run the stock air tube without the air box from the carb as long as the air tube is hose 'clamped' or 'zip tied' in the oscilation area. This may even provide another 2 horsepower - this according to Mr Horsepower. I talked with Randy about this, and he's going to re-test it with that set up. If it works out, he may even provide a support bracket for the air tube in his pipe kit .

Randy says he is still at least 4 weeks away, maybe 6, before he's ready to sell them.

This is only meant as FYI. I hope I dont make anybody upset.

 

Will you be able to run this exhaust with dual carbs???????? remember most guy's are migrateing toward the duals???

 

I dont even think the duals, or any other carb, will have a problem because the pipes are routed so low to get through the mid frame. They will actually have a slight bend down right about where the carb mounts to the intake manifold.

 

If i order a set and they won't clear the carbs do you think someone like say OD will take them back???

 

We are all going to know, when they are available, if they will clear the carbs or not. I'm getting the first pipe and I will post TONS of pics so that everybody will have all the info they need to make a good decision.

 

how are they routed? like the pred ones inbetween the subframe or on the outsides like the rest?

 

They are routed on the inside of the subframe for the DS. Sorry, no chance of that changing.

 

That sucks man, Guess im gonna have to find another pipe for my bike. Cant go without my airbox.

 

The target market for the dual pipes are the dune riders because of the need for quiet ops.

 

Yee-haw!! I was hoping for them to be on the inside, I love the way that looks. Man I can't wait to get my new bike, almost time guys!!! Baja X here I come!
