EXPANSION CHAMBER EXHAUST DESIGN

[Fast Feddy]

i just got this great software to design my expansion chamber exhaust system on my vespa :winner:

2 Stroke Wizard Tuned Pipe expansion chamber design software is used to design the tuned pipe exhaust system of any 2 stroke engine. One can choose to design a two-stage or a three-stage diffuser chamber according to requirements.

I think it is great software for this porpuse and at only $39 (25 euro) a bargain too!​

Hm, looks to good to be thru.
Can you give us hard figures on performance?

i will still get my exhaust made at a local welder ... i got hold of the software after a friend had pipes for his RD350 made using this program, and he got much better performance now, than with his old aftermarket expansion pipes he used before.

he got hold of the program while holliday in thailand ... many use it there

Doesn't make it a good programe. The thing is, CVT engine exhausts work "different" from a geared bike exhaust.

Could be a good program, but there are alot of factors that have influence and that are not asked for.
