Hi guys,

Recently I drove along side a Renault Megane RS along the sprint highway and I noticed his exhaust was firing whenever he up shift or down shift. The firing was very minor, not like those Lamborghini or Racing Cars, it was small but visible and he was cruising fairly usual, he wasnt upshifting hard or downshifting in high revs. It looked pretty damn cool from my view and I was curious what mods did he do to make his exhaust fire mildly...
