So just to clarify, You start your first thread about the muffler not fitting correctly, then you hijack another thread to trash Bisi some more. I guess that's not enough and you start another thread to throw Bisi under the bus again. We are not seeing both sides of this story unfortunately. Bisi stated he would make it right. Are you the kind of guy to call the number on the side of a service truck and demand the driver be fired because you didn't like what he did in traffic? Its not $1000000.00. Why be a dick about it? My pulse chamber fits perfect. I find it a bit too loud for driving out the street Sunday morning at 7:00 am for breakfast with the wife. I ordered the sound arrestor. Ill try that, and if I don't like it I will pull it off and stick it on my fireplace like a piece of art.
