Hi guys been reading alot of the threads lately and the pics etc have given me loads of ideas in how to subtley modify my Clio. Cheers!!I have a RenaultSport Clio 172 ph 1. (00 model)I want to put a backbox only on it and was wondering if any of you had done this, and if so what changes if any does it make to the sound , not really performance. Any replies would be appreciated. Please dont reply if you havent done so or know of it being done, only experiences please. Thanks guys
