New Exhaust

I'm in process of buying a exhaust for Mk1  golf gti sportline , been looking for while couldn't make up my mind . Stainless steel supersport exhaust has come up for sale on eBay looks really good quality , and at decent price only thing is from Germany so need to get this right!!!! 
Will the exhaust fit ok ? Will I need any adapters ??  

General opinion on the exhaust would be great.
