ppp exhaust upgrade centre pipe

[ludey dudey]

hey peeps, ive got a full prodrive system on my car & need a new centre section fitting, ive found one i like the look of http://www.ebay.co.uk/itm/Milltek-Impreza-Turbo-2-0-WRX-STi-Exhaust-Stainless-Centre-Link-Pipe-MSSUB114/330459588569?ssPageName=STRK%3AMEBIDX%3AIT&_trksid=p2060353.m1438.l2649

but am getting confusing answers when it comes to gaskets etc, ive been told on the back box end il be fine with a 2.5inch gaset but on the cat end i need a crushable gasket?

 

anyone able to clearthis up for me please..

thanks

Back box side you will need a standard exhaust gasket, on the cat pipe end you will need a doughnut gasket
