    You'll need 2 downpipes and cats to start with, can get some good systems from the states, I run a cat-back 3" Vibrant, with Labree downpipes, i bought the catback for around $400, however the downpipes are the expensive bit, I was lucky, my downpipes and cats cost $1600 new, but i got a US ebay bargain for $400. The cheaper option is to gut the pre-cats in the downpipes therefore freeing up the flow but keeping the original downpies, then de-cat the main ones, or have some hi-flow ones welded in, or if you can find a set get some RS4 downpipes, again gutted precats, but they run a slightly bigger bore and 200cpsi main cats.

    There are loads of options out there X-Power have a system which people have said works well providing you get a pro to fit it due to some bad fitting but in all it is said to be a very good system for the money (£750) have a look on RS246 and AudiSRS.com

    The XS power system can bit hit or miss, i think the general concensus is that they have a number of jigs, some of which are perfect and others arent. If you get a system from the good jigs, your good, if its from the **** ones its a bit of an ****.

    I went out in an S4 last night with a full XS-Power exhaust system fitted. It's too loud for my liking, but certainly on this car was good for over 450bhp!

    I should mention, the guy has had an S4 previously and had also fitted an XS-Power system to that one. Completely standard apart from that, it got 270bhp on the rollers (when other standard S4's on the same day had barely made 260) and had done high mileage.

    He said the first system fit easily, but with this one it was a PITA and one of the downpipes hangs an inch or two lower than the other. He's going to an exhaust place to get some flexis welded in and getting one pipe made a bit shorter so they fit equally.

    Saved himself some big bucks over a Milltek, and still has a very well performing system.

    Hayward & Scott. Custom fabricated by the automotive exhaust Gods. What these chaps can't do with an exhaust system you could write on the head of a very small pin. It sure as hell won't be cheap but when you're looking at 2k anyway it's got to be worth a phone call.
