Piper make the new lot that GDI have, I was speaking to Gary at Piper regaridng gettting one and was told I had to go through GDI which is fair enough.
I love the Piper gear, well made and not silly prices, I had one fitted to one of my old cars and it sounded really nice. Well worth the money if your having to replace the OE System due to the crap design and materials that Renault use.
