miltek 1.8t exhaust- confused now!!!!!!!!

hi i just bought the non resonated system just checking that i should actually only have a rear silencer and that the middle one is replaced with just tubing or is this wrong please help!
 
My Milltek cat back system is not too loud but definetly better than the stock! Its just polite, not to lairy but nice! Can't complain! Had a blue flame before and it was marginally louder, but I think I prefer the milltek!
