Yea, my friends RX7 has afterfire and hes running stock engine with straight pipe exhaust (IN has no emissions tests)
anyways... I want to know how to achieve some bad ass flames popping outta my exhaust when I rev it, or when I am flooring it.

something like that. I know its due to unburnt fuel buring from the exhaust heat, but how could I achieve this?
