Hey guys, in the next week or so i'm going to order a Milltek Exhaust system for mt 2.0TDi, but dont know the ins and outs. I dont want a really loud sounding car after, but dont mind a bit of a nice 'genuine' roar when i put my foot down. Basically nothing that sounds way over the top for what it is, but what will give best performance. Ive also seen sellers say 'large bore downpipe' and 'hi-flow cat', do these offer an improvement? Looking on eBay there are 4 types i can see-: CATBACK NON RES CATBACK RES FULL NON RES FULL RESONATED Can anyone point me in the right direction for the outcome that i'm looking for? And finally, i've only been a member here for a short while, and would like to thank everyone who gives there time to help others out, it's been an amazing help with my first Audi!
