I have been asked a couple of times what the Ebay OBX Catback sounds like on the ST205 so I thought I would start this thread to upload sounds in case someone is interested. I have been waiting until I got a drive by but it won't be soon so I thought I should upload what I have and add when I get more.

General fit etc was excellent and I had no issues with rattles. I had the flex pipe replaced and it wasn't done exactly right so I now have a slight rattle when starts up so it must have been a very tight fit to begin with. I noticed lately that I have a popping sound when shifting when the car is warm but I need a new lambda so I am attributing it to that. It runs very rich at the moment and I had not issue with this noise before.

The only real issue I have is that there is a whistle at around 6500 rpm when I have the silencer in but it isn't there when it is out. It sounds like it is coming from under the hood so it may be that I have a leak somewhere that I can't find.

These videos were made using my phone...static etc but all I have at the moment.
