I guess I'd really have to ride both exhaust systems (TL's/TBR's) and the the stock OEM to really determine the difference.

I was looking at the TBR's on Wingstuff.com and there are some bad reviews about them; regarding the fitment and the quality that some people have received recently.

The problem with returns is that you may end up receiving someone else's return when you order. Sort of sucks to pay for a new item and then be shipped one previously owned.

As an aside, I will be carefully scrutinizing my ElliptiGO when it arrives this Saturday via Fedex from Kalifornia. If it was a previous return... it's getting shipped right back to them.
