Chap on one of the Australian Celica forums has just bought himeslf a nice looking Group A GT4. A small 'complaint' he has is about the boy racer 'pttttssssshhh' noise it gives off. He was correctly under the impression that it couldn't be heard on the standard set-up.

... which would obviously allow a certain amount of noise. However, mine is a similar set-up which makes more of a 'flutter' noise than anything else. What gives me cause to beleive the noise is coming from somewhere else is this...
I've never seen one of these on a 205 before so can only come to the conclusion that it is aftermarket. Anyone wish to comment?
