Question about Honda gx engines

[timt]

I have two Honda gx 140 engines on my kart and I want to install a performance exhaust on them. The problem is only gx 160/200 are listed does anybody know if they will bolt on. I've talked to the company's that are selling the parts but they don't no,any info would be appreciated. Thanks

i looked at some exhaust gaskets for a gx140 and they are the same gasket for a gx160/200 so that must mean the flange is the same size. so the exhaust should bolt on. the only problem i can think of is the brace might have to be modified a little but thats easy.

exhaust gasket:
HONDA 18381-ZH8-800
Fits Models: HONDA GX120,GX140, GX160 and GX200

I have a gx140 & a gx160 & both mufflers are identical except for the brace (as mentioned by bluethunder)

Thanks Bluethunder and Fabroman for the quick replies. Gonna order up the header and muffler tomorrow and I'll just weld up a brace for them.
