   dont waste your time mate.
   
   just wait and get the proper centre section.

   already wasted my time, fitted it today, does the magnex centre section increase the noise at all, just doing it for the looks dont really want it to be to much louder than standard?

   haha
   
   nope as it has the silcener in, will be a better fit and better sound.
   
   Standard centre is very restrictive also, so if want the most from it, get the proper centre.

   is it just the centre section? from the cat back to the back box? As i dont want a straight through de cat? Also for the people that want to know for future reference the reducer needed to fit the magnex backbox to a standard centre section on a vtr is 55m/2.25" to 42mm/1.75".

   its the centre mate so will leave your cat in and the centre is the proper magnex and has a silcener in it.
