Honda Gx390 vs larger V twin sound levels

I have a Gx390 and a predator 420. Once you go up to the vtwin engines like the Honda 630 or Kohler twins are they much quieter? Thanks for your input.

I find my GX690 main unit and GX340 backup to be equally loud. Perhaps someone who is running both side to side can chime in, but I don’t think the difference is much either way.

Thank you sir. I was hoping it was for a noticeable difference.

I installed an 18 hp engine in our golf cart. My wife hated how loud it was. I found a smaller car muffler to put on it and it’s super quiet now. That might be something to look into. I would just install it under the trailer so your machine doesn’t look white trash…lol

Can’t speak for the honda vtwin.

But my gx390 is louder than my 18hp vanguard v twin

If your worried about disturbing neighbours while washing, it’s a waste of time, you could have 11 mufflers there will always be that select few that complain no matter what you do.

I second that. :+1:

Just tell him to wear ear plugs! lol

Just because you Air Force guys are into that funny stuff doesn’t mean you’re talking me into it. You’re better off watching Broke Back Mountain with the rubber scrubbers.
