There is a rattle that sounds like it is coming from under the passenger seat that is very annoying. It only rattled everytime i made a left turn so i didnt really mind it. But after I installed a test pipe, the rattling in the interior became way more frequent. You can only hear it from the inside and when the top is up. I know its not the seat belt and the glove compartment. I checked under and behind the seat and there is nothing under the ordinary. I emptied the trunk and the spare and it is still there. I dont know why a test pipe increased the rattle? Maybe because its right under the passenger seat? Does anyone have any ideas what it is??

Thanks
