You have been looking for ages and we have them finially.
The test ones have been done and the production is about to start.
These are about 4 weeks out from shipping so like normal we have done a pre-sale on them.
If you want to get in and buy them then hurry. We are only offering a limited number in the pre-order and then the price will go up
Price includes worldwide shipping
These will fit a Yamaha 701 superjet (61x ) and also a 650 (6m6)superjet engine.
The header pipe hole in this manifold is 46mm
They will go on a 62t and 64x but of course like always you have to screw in the helicoils to make it happen
We have found that the outer top holes on the manifold where it bolts to the cylinder are tight and may need to be enlarged slightly to go on. a simple pass with the 9mm drill will fix this issue if it effects you.
We will have a header pipe coming soon with preferential pricing for buyers of our exhaust manifold/ We will support you if you are supporting us by wanting to buy both
