I have heard from several sources that the Bell stainless systems are superior in quality and fit to the Falcon.  The TransAmeriCan Stag used a Bell system, and I was pleased with its sound when I rode in and drove it.  Don't recall any annoying resonances, but my memory was never any good.

You may have noticed at Triumphest that TR44SUE is louder than your bagpipes. Sue is getting tired of setting off car alarms with the glass-pack system that Chris Murphy commissioned at the Midas shop in San Antonio.  A Bell system may be in its future.  Anybody know the best way to buy one in the USA?

Meanwhile, how goes the battle to either move your Triumph home or secure it in Colorado for the winter?
