Sorry if this is under the wrong topic but it looked like my best option. I got an APEXi WS universal and had it attached to my 2.25 inch piping with a resonator because it was marketed (and rumored) to be reasonably quiet. Actual results are much different. Sound output and tone vary depending on temperature and engine load. So, I was wondering if there was a silencer or something that would work for this muffler. I know APEXi doesn't make one for this muffler but I was hoping for a universal or something that worked well. Right now, shutting this thing up is more important than performance. Thanks for any help (or any suggestions) on quieting this thing down.
