ibb88 and others: i literally spent 40+ hours going over every single S5 B8 exhaust vid on the internet when i purchased my FI resontated exhaust setup. What i can tell you is that the FI, AWE and Akrapovic are some of the best sounding exhausts on our cars.
1. The Akrapovic for the $$$ doesn't come close, as it's a slip in mid underbody and doesn't do much to increase exhaust flow. Their ad sure as crap sounds sweet..in real life it doesn't have the same effect...gotta love edited videos
2. The AWE has a Track and Touring version...both are amazing, and are worthy of consideration given their price point...nuf said
3. The Fast Intentions (FI) is the only one to come with downpipes and increases exhaust flow over the other 2 setups. A little pricier, but worth every penny.
There were questions about Res vs Non-Res. I ordered mine in Res form knowing i could cut out resonators if need be....easier to remove vs add. What i can tell you is this as i've since cut out the resonators: when the resonators are on, would be comparable to attending a concert hosted by the greatest singer known to us and listening to it while standing in the bathroom...a little muffled, a little baffled, a little inhibited. When you pull the resonators off the FI system...WOW WOW WOW is all i have to say, it's like sitting front row of that singer mating with AMG (Mercedes)....it's that good. AWE Track is a brilliant exhaust...but doesn't hold a candle to the Non-Res FI exhaust.
I will not argue with anyone on this forum or others. Proof's in the pudding. My exhaust gets compliments daily. I have people stopping me mid-drive to compliment my car on it's exhaust. I weekly will let my wife drive it getting groceries, but stay on the driveway just to hear it pull away...it's that good. The FI non-res exhaust realistically needs around 1500-2000 miles to really break in, no drone, pure audiophile orgy. There is no better sounding 4.2 Audi S5 B8 car....none.
Apologies where i live it's always windy and my wife won't help in filming:
