I've had my V&H Ovals on for about 20k miles and love the sound.

 

V&H slip on mufflers have a removable baffle. V&H slip on ovals (with the rounded oval piece extending past the end of the muffler) also have a removable baffle but it is short and there is no quiet replacement and no way to add material (fiberglass) to reduce the level of sound. Slip-on baffles can be removed and replaced with quieter baffles or you can add or remove the fiberglass packing. V&H does not not make a quiet baffle for the slip-on ovals and they recently emailed me and told me that they had no plans to make one. I started with BUB Sleepers and thought they sounded like a dump truck trying to make a grade. So, I bought the dual headers and slip-on ovals because I heard them on a stock FI 05 in a parking lot. Then I incresased my Cu In to 95 and added the 203 cams to my carbureted electra glide. Now the slip-on ovals are loud(period) I most often ride 100 miles (+) each time I go out. The other day I traveled 350 miles and the pipes seemed louder and they are becoming abnoxious. I just replaced the ovals with my BUB's and they are quieter on start up but they now make a stronger sound, more Harley like, but they are also louder than in the past. If V&H made a quiet baffle for the slip-on ovals I'd buy one because I think the ovals have a great look. Until then the Bub's stay on, and maybe I'll try something else. Remember the sound is in the ear of the beholder.

 

I have added SE touring slipons and I am very happy.

Some JB weld on the ends to make the holes smaller....That should do it.
