Hello everyone, could someone tell me a website to buy a stainless steel vertical silencer? Thank you.

For your 702?  There isn’t much of an aftermarket for stacks for direct fit.  Sometimes custom is king.

If it is for my 702, I would like to buy it finished since I do not have the material or machinery

Joe's Racing Products makes a nice racing muffler. Designed for use on mini sprints powered with motorcycle engines. Not stainless. Se my hot rod post for pictures.

Carlos,  I understand your struggles being outside of the US, working on a US based piece of equipment.  Do you have access or a source in Spain for US thread (NPT) pipe?  Your Kohler engine’s exhaust should have a 1” npt outlet.  We generally start with a piece of pipe and a 90 degree elbow, then build a stack, with your muffler of choice.  It is good to clamp a support rod onto the pipe, and bolted to the engine to help with the extra weight.

Here is some inspiration, if you will.  I used a 1”x3/4” PIPE BUSHING, then 3/4” pipe.  This is all BLACK PIPE not galvanized.  I ran a STREET 90 and welded a tank spud (female pipe thread) into the automotive glasspack muffler.  Many people run a standard 90 and a length of vertical pipe, and clamp a muffler on.  It’s all preference.  You can see the clamp on support I built as well.  It is steel tubing, with small tubing welded perpendicular, then slit on a saw to create a clamp when bolted together.

I have used a 1" X 1/2" X 1" black iron pipe T with a 1/2" pipe plug drilled and tapped to support a stack muffler.

Hello again, this afternoon I investigated in my country and I can surely manufacture one, just one question, do you put some fiber inside the exhaust to reduce noise to just the hollow tube? Thank you all for your quick answers, we are very far away, but at the moment very close time, greetings to all!

FYI, racing mufflers have a straight thru (meaning you can see thru from one end to the other) perforated tube inside a bigger tube with insulation packed in between the two. During engine acceleration the exhaust is louder but quiet during constant RPM.

Thanks for your explanation, mate.
