16hp briggs exhaust

sandbarpete · 11-12-2013, 10:13 PM

just wondering if there is any horse power gain from a stock exhaust system to a aftermarket one for a 16hp briggs

Apparently there is, but for the high cost, I can't see spending the money on it. I've always made my V-twin pipes using the stock header pipe, then going to 1" copper pipe/fittings after that. It makes it easy to build so I can clear everything 'under the hood'.

I made my neighbor a exhaust for his 16hp B&S from 1" conduit pre-bends from depot.

And yes when you make these motors where they can breath, they will come alive.

If you will just remove the burrs and sharp edges from the intake and exhaust ports on the block it helps.

Not too sure how restrictive this is. It is off a mower with a kawaski motor. Sounds pretty good. With a bone stock 16 hp I can run 28 MPH and get there in about 200 feet or so.

Looks good to me.. it is always better if each cylinder has its own pipe
to the muffler, but I haven't noticed a big difference in power, and I have had them both ways.

BTW those are nice mufflers off that mower, expensive too. They aren't as quiet
as some generator mufflers, but that is probably a good thing..but they are nice.
