I have a honda 24 HP GX670 V-Twin and my exhaust has compeletely deteriorated. The Honda exhaust is so expensive i was wondering if anyone knows of a place that would sell an after market or custom exhaust...also, i am looking for a few more HP and i was wonndering if anyone has had some luck with a particular air filter. Thanks

K & N not so much help, I had my heads ported here locally and installed an advanced timing key on my Honda 24
Heads helped the most
Exhaust no aftermarket "off the shelf" gonna have to have a custom built.

Keep in mind the Honda is tuned lean for EPA bullshit If Honda is your ticket I would study real
Hard at that carb situation....

make your own. remove muffler, cut flanges off and weld 'em on two straight pieces of pipe with threads on one end. Buy two $7 screw on mufflers from hardware store. done.

Hey check E bay I just got a after market stainless muffler for my 20 HP Honda for 80.00 dollars. On a bid
