I had Longshots and a Kuryakyn Twin velocity air cleaner installed on my brand new '02 Midnight Star at the 600 mile service (July '02). The pipes are a LOT louder than I expected. My riding buddy says they sound really good, but are almost obnoxious when I pass him or ride just ahead of him. What I did was to fabricate some very simple baffles and they quieted the bike down a bit. I took a flat, brass door strike (the one that a door's dead-bolt goes into) and bent it into an "L" shape. Make sure you use a solid brass one and not the cheap, stamped sheet metal type. After you have the brass bent into an "L", place the screw hole on one side of the "L" onto the screw that secures the stock V&H baffle (still installed). Put a dab of "Form-A-Gasket" on the screw threads and secure with a nut & lockwasher. Repeat for 2nd pipe.
Believe it or not, this really works. The bike is still very loud, especially when you "get it on", but it's a bit quieter at idle & cruising. It works by disturbing the outflow of the exhaust. As an added bonus this provides some extra back-pressure, for increased torque. This will work well for those who like a louder sound,and run without baffles as well. Here again, this will restore some critical back-pressure for improved torque in the low to mid range.
Exhaust gas analyzation at Yamaha says carb adjustment is still right on. The bike runs great & sounds "most excellent". I removed them a while back, to see if the sound improvement was just my imagination. Nope...definitely quieter with them on, so reinstalled them right away. Again, it's not a huge difference with or without these things.
For illustration, suppose 100 decibels is the legal max. I'd guess the Longshots with their stock baffles might be 105 decibels. Adding my baffles makes it 99 decibels....I still take it real easy when going by a cop. In the sketch, top drawing is the doorstrike - you probably have one laying around the house - or available at a hardware store. Middle drawing is the strike bent into the shape you want. Bottom drawing is one of the exhaust pipes, viewed from the rear, with the new baffle bolted into position.

Made my own baffles for V&H Longshots HS And reduced the noise down to 92 db. Still has deep rumble but the harshness has gone . Used 4 reducers 2" o/d - 1"1/2 i/d, 2 x 5" long x1 1/2' o/d exh tube, 2 x 10" x 1 1/2' o/d exh tube and 4x 1 1/2" saucer type engine frost plugs. Total cost of materials $24

I put quiet baffles in my longshots but after batwing fairing and ultra kit I was getting more noise than I liked so I modified the baffles by adding a 6" 1- 1/2 pipe with a 3/4 washer cut in half. Welded on both end opposite each other. Tac welded to the front of V&H Quiet baffles. Now I can hear to radio a interstate speeds.

I just installed my longshots, and used this idea to add some backpressure, I picked up 1/8" steel pc (1 1/4" wide) at Home Depot, and made a L shape with each end about
1 1/4" square, painted it with the BBQ paint and installed it onto the same bolt hole that you use for the baffle (had to use longer bolt), install the slash tips and done.
So far (i did some test run in the back lane) no backfire on decel, and low end power is still there, the pipes are still nice and loud.

Sad to see otherwise responsible riders still making the entire motorcycling community look bad by irritating everyone with their loud pipes. I like a good sounding exhaust note as well as anyone but what I hear from 90% of the bikes with aftermarket or modified exhausts is nothing but obnoxious noise. Noise does not equal power. Noise is fatiguing for the bike occupants and those riders following, it permanently damages your hearing and is generally disturbing to all others. Many campgrounds and gated communities will not allow any motorcycles on their property due to complaints from their residents about motorcycle exhaust noise.
We're a heartbeat away from the federal and local governments passing legislation prohibiting any changes of a motorcycle's stock exhaust system; even those that would have no effect on the sound. Why give them more ammunition to make this happen? Let's be good neighbors so we'll be welcome wherever we ride.

V&H makes a really nice set of 2" baffles for about $52.00 a pair . I put them in a set of 2" home made drag pipes and they work very well .
They are called longshot quiet baffles . you can find them @
