Followed a WRX today...

It sounded hideous & when it turned off the dual carriageway it had flames coming out of the exhaust, looked really daft, what's all that about then?

It wasn't happening all the time, just when he slowed & turned off. I hadn't heard of or seen a 'flamer kit' before, Google has though and those things don't need to exist, but I guess that's what it was now & my initial thoughts of the driver seem to be correct
