Just wondering, but what makes a spark come out a few cars exhaust?

Do they have to be heavily tuned?
Do any fiestas do that or does it depend on what exhaust/engine you have

[Mav Singh]

i believe a natural spark or fire will come out of a cars exhaust if it has been tuned very highly but eveyone i see used flamer kits and cheap tricks for looks.

over - boost and then change gear...... POP POP BAAAAAAANG

as my poor little ears can testify after a full on blast through the dartford tunnel in a 400bhp evo

Cossies will flame naturally, because of fuel being used on the over run. You could get your FRST set-up like this, but you have to make your exhaust very hot for flames.

Use a flamer kit for best results

if you have alot of back pressure then when you deaccelerate you get a popping noise from your pipe, thats excellent. thats an irrelevant posty, just wanted to let you know what my pipe does
