I can make a muffler to make the mod pipes alittle more friendly. Here is what you have to be carefull of, back pressure. They do not like back pressure. I've been here and have the t-shirt. So it's a very fine line you can walk with these and not loose power. I had a rs mod with twins flowing through a modified stock muff, sounded sick and ran great. Email me or pm me for details.
