When in Vancouver yesterday I went to an old bike shop and found the same Mac exhaust in a box that I had just shipped back to FL.
The engine mounting flanges were loose and spun around easily, so I called Mac and told them about the system I received with the flanges "welded" to the pipes in the wrong direction. He immediately said just hit the flanges to loosen them up, they get stuck on sometimes when the chrome is applied.
I said to him you should tell all your dealers this trick so people don't ship them back after talking with the company they bought them from!
I called the dealer who said, sorry if you want them, you will have to pay shipping again....for the 3rd time @ $65.00 per trip.
I called Mac back and told them their dealer told me to go pound sand on the shipping cost to get them back to me.
He said he would try and see if Mac would pay to get them to me. Waiting on a call.
I did tap the flanges a bit with a rubber mallet, but I didn't want to break them if I was going to have to send them back.
