1981 XS400 aftermarket muffler issues

[Laban87]

I recently purchased a 1981 XS400 and was unfortunate to have the stock muffler crack and eventually separate completely at the rear weld connecting the mufflers. I purchased VooDoo 19 inch turnout slip-on mufflers. I hacksawed the stock exhaust where it was welded to the muffler up front. The installation was fine but I found that the muffflers themselves are incredibly loud because of a lack of baffling. I have considered many options but have not pulled the trigger on any baffling modifications. This is my first bike and I really want to ride. I need options for creating baffles for these mufflers. I cannot slide aftermarket baffles in because the small ones in there are welded in and block the path. My current idea is to weld a washer on the inside to create a smaller exit hole and get some air shooting back in. The difficulty with that is with the turnout style of the mufflers which makes putting anything round in difficult. I am open to any ideas and REALLY need help. Thanks!!!

Most of those type mufflers are way to loud and will get you a ticket. They even will make the bike perform worse. Remember if the price is cheap (under $100 for the set) the quality is also cheap. Either try the washer thing or get a mac set that has removable baffles. There are other sets around also. Remember that stock is always the best

Those turn outs are extremely obnoxiously loud forsure.i had a set on my bike they were quickly removed and replaced.

Try shoving a stainless steel scouring pad from the grocery store in there. Could cause some performance hiccups, but maybe not.
Don't use fine steel wool. It'll just melt in the heat, and it's a great fire starter. Stainless steel scouring pads for dishwashing is what I'd try.
