Sorry lads,
I've been on the site loads but never seen the replies. The conversation is simple with an original GTi exhaust, mine literally took 15 mins. The only thing bar the exhaust required is the rear valance which I bought from VW which believe it or not was cheaper than the non original ones on eBay etc lol think it was £40 odd inc. towing eye cover.
The noise is just the same I think but I'm happy enough as I only done it for looks anyhow.
Still have the original GTD exhaust here it's in perfect condition.
