Good afternoon everyone,
We’ve completed testing of our prototype B8 exhaust systems and are moving onto to final jigging before we schedule a production run.
Here are some pictures of the production exhaust systems. All systems will be available with standard Polished Silver or optional Diamond Black exhaust tips.
Single-Outlet Dual-Tip System
This will fit all sedans with the stock valance in place.
Each tip is individually adjustable, so stagger and depth into bumper can be set according to personal taste. As you can see in these pictures, with the right adjustment, slash cut tips are not required to blend into the bumper, and the straight cut gives a nice subtly aggressive edge to the visuals.
Test driving with the full system has proven to be extremely civilized, significantly more so than our B6 or B7 systems. No loudness at any rpms that could be objectionable to some people.
Dual-Outlet Quad-Tip System
Thanks to the help of a forum member, we were able to acquire a B8 S4 valance sooner then originally planned and were able to move right into Quad Tip exhaust prototyping.
This will fit all S-line cars with a B8 S4 rear valance.
Dual-Outlet Single-Tip System
This will fit all avants (S-Line and non S-Line), as well as any sedan with the avant valence in place.
And here is a dyno sheet showing wheel power. Notice that in stock form, we are seeing 193hp to the wheels on this car, which STRONGLY suggests that the engine is underrated from the factory at 211 crank hp. That would suggest only a 9% drivetrain loss for a quattro car, which is unrealistic. It is more likely that this engine is making around 230 at the crank, which would also suggest that our 7 whp gain translates to about 8-9 hp at the crank.
Also, we have found that the stock downpipe uses a straight through resonator, and there was not much power at all found replacing it. We will offer all our systems with and without downpipe as our downpipe affects sound volume more than anything. Pricing will be announced by week's end.

Hi...
That looks great. The dual tips really do look class.
The engine output graph shows stock as 193 whp and 214 Ft-Lb torques.
As you say Audi must be under rating it's power output.
Audi quote 211ps and 350Nm from the factory at the crank I presume.
Can you quote from your graph what the actual Nm or Ft-Lb torque the engine is giving out from the crank.
You not the first tuner to be quoting an increase on the Audi factory quotes.
Will your exhausts be available in the UK at all, if so how much for your standard set up (twin exit).
Many thanks
Martin

To me what matters is the difference between the stock and AWE exhaust, the actual HP/torque #'s from the dyno might be off -- and even if that is the case the difference is still meaningful.

Dude... that quad-tip exhaust looks PIMP! I gotta hear how it sounds though, I have no doubt that it roars but I'm just curious to see what you guys have been able to do with the B8.

Martin,
You can multiply the numbers you see on our dyno chart by 1.28 to get crank numbers. This will translate to 8-9 hp and 6-7 lb ft of torque gains at the crank!
Our entire worldwide network of dealers will have access to our B8 exhaust systems once we have officially released them. You can order any A.W.E. product through your local dealer listed here: here:http://www.awe-tuning.com/pages/info/aweinfo_dealer.cfm, or by going through us directly.
<o></o>Pricing has not been announced yet, but stay tuned as it is coming shortly.
