Hi to all
I¢ž¢m having an exhaust 4 in 1 built at home and oval muffler on it but I don¢ž¢t know what the difference is between a round muffler or an oval muffler
I¢ž¢m now making the new muffler
So I want to now is the shape meter for performance
I want to get max performance from my 1.6 sohc engine

The design is much more critical than people think, so - sorry - I am going to advise you NOT to try and make the muffler.

Read the thread on sohc carburation and you will see what I mean.

The best for your application os the same one used by James Bowen.
