The clio doesn't "pop n bang" much, the engine is not tuned for that (ignition timing, cams etc)...
I'm fitting the 172 Supersprint this Saturday morning or next week too, so you'll have a few videos from me too.
I'm very curious about the sound and I'll probably put the car on our MAHA dyno to have real figures, but I don't have a stock exhaust to compare it with. Plus I'm fitting it with a sports cat and 182 manifold.
The 182 system is costly, I agree, the design is more complicated than other systems, with the separetd endpipes, the Y pipe inside the transversal box...it's been designed that way to match the homologation noise levels (E1) ,but for the UK market maybe we could make a different one as we have just done with the 172?
