Bassani X-pipe Tick

I bought a Bassani off road X-pipe for my '95 and put it on the other day. Ever since then I've had an annoying tick that sounds like an exhaust leak, but everything has been sealed up tight. I've got another car with a BBK X and have had no such tick... so I'm stumped. I took it in to the local exhaust guy and he welded the X where Bassani originally had the clamps and it didn't make a difference. I've jacked the car up in the air and started it to listen for where the sound was coming from, and it seems like the tick is originating from somewhere IN the X-pipe.

It's driving me nuts... so anyway, has anyone else had this issue? :shrug:
