Ever since i decatted and uprated my exhausts and added a HKS air filter and hard pipes, when ever i am booting it along and drop from 4th to 3rd i sometimes get a back fire even though my car sounds awesome i was just wondering why it does it. Also i had a mate following me on his motor bike once and he said there was a strong smell of petrol in the exhaust fumes and i have noticed this to. Is it running to rich and what should i do to sort it??
