lol, cheers Ric... my car doesn't have twin webbers though, it has a single webber. 
I don't know why it is that loud.... but loads of people have told me that it's one of the loudest cars they've ever heared. 
It is louder than my Skyline... but only because it has a standard exhaust... and as for my celica.... that was louder (From knocking from the engine
) untill it blew up on a round-about.
New engine time for that methinks.
