My 88 i just bought has a 4 into 1 Yoshimura pipe, not exactly sure which one. It sounds good, but living in a VERY quiet neighborhood, the locals don't like me firing it up for work at 6am. She is very throaty sounding. Any way to quiet it a little bit or should I try and find a stock set of pipes or aftermarket dual pipe set up? Any help will be greatly appreciated.

Have you tried repacking the muffler with new STeel wool? This pipe may not be the type to use STeel Wool but that was a practice with AM pipes back in the day. Used CBR mufflers can be found on Ebay.

Many thanks, will check into that. I called a couple places near where I live about the stock pipes, one was a bike salvage place. I'll keep looking around. Thanks again!

In a previous life I would roll the bike down the street before starting. Away from garage doors or walls that would reflect the sound. Other than that get new neighbors!! As long as the db level is below the legal threshold and your not "tuning by twist" not alot a neighbor can do. I know that most neighbors are cool but there are usually 1 or more who will take offence just by the sight of your bike let alone the sound, For them I say screw em! Did I mention how much I hate HOA's ........ sorry differant forum. But really to set up your bike to please you neighbors is wrong I could see if it was say a big single or twin with open megaphones but any four at idle really isnt all that loud even with a race pipe. If you idle away till your a block away or so whats the harm.

If you think your Yoshi is loud, you should hear my s/steel 2" twin pipes !! I just idle it off down the street, and open it up when well away.....I often ride early, and there're little kids who need their sleep, so I consider them, not their "old fart" parents........(I'm an old fart myself)
If you're worried about it, tips above are good, otherwise a cork or f/glass plug will be OK for a short distance, and don't rev the bike, the back pressure could do damage, but at low revs it'll be fine.
