hi guys.. first post i think!! 
i have a '00 clio 172
first of all sorry for my english, im from portugal!
i bought an used 182 exhaust manifold and now after reading a lot i´m a bit confused..
what´s the best rear silencer box for a 172 engine with a 182 manifold??
the idea is to take out the cat too!!
.. how much gains can i expect (after reprogramming the ecu too) ??
tks in advance !!
