muffler/expansion chambers

[guest11]

does any one have any info on making a kart muffler?

I've never made an expansion chamber, but have paid plenty to test different versions over the years!

Check out www.kartpipes.com.au/ for some info to start with.

From what i've experienced it's all well and good to have the theory, but sometimes a pipe will be fast that doesn't appear to conform to any conventional theory!

Another place you can look for ideas on exhaust chambers is:

I have used KT pipes made by Ian in the past with good results.

Let us know your progress if you decide to build your own chamber!
