It doesnt look like any of the aftermarket exhaust ive seen. The text looks French so I would say its made by a French company and possibly even custom. The translation of the text gives no clues either.
I emailed the guy ages ago when i came across the video this was his response "It's exhaust Madac, with inter tube and décat pipe the best for clio with orbisound" your guess is as good as mine :mrgreen:
