Its really simple tbh you need a straight bit of pipe (i went for 54mm) i bought it from a local car parts place was £14 for 2 meters, a tip think mine is a 2 inch tip that cost £7.99, and some rod to make hanging brackets i bought some off ebay a while ago for about £10, Then took the back box off sat the pipe inside the flange weld round it, the hanging brackets make 1 or 2 cut them to size and weld them in place then fit your tip really simple took around 10mins to do just make sure when you weld it in to the flange make sure the pipe looks like its in the center of the cut out (if you have one) as for noise its not really loud i can hear a difference but its not massive, i would like it louder tbh but hoping and empty cat will make it louder, i noticed a difference in turbo spooling up tho, will see what noise is like when the empty cat is put on if noise is not different then i will be tempted to empty the center silencer
