nice gains! Did TQ increase by about the same or stay the same?
What happened to the air fuel ratio?
That sounds like the devil breathing.
Congrats!

Tom - plan on taking it to the track.. yes. Getting software in 2 weeks though, might wait until then. Going to dyno before and after software as well.
Jay - I personally don't have pictures. USP Motorsports took lots of pics and vids of the whole project. They will either get them to me or you can call or email them directly. Their contact info is on the video clip.

Your worst nightmare...
^^ so you guys are the ones with the famous S4 with the VR6 motor. 
Does the S4 have stock axles and everything else? I can't stop watching the lauch and the way that thing squats, I could have swear something was going to break. LOl.
Very nice exhaust system for the V12, it is a true work of Art!

We have not confirmed fitment on the 06, but I dont think it will fit because the w220 is completely different

Is this dyno right? Looks like 19 peak Hp gained and it looks like you lost hp and tq down low? Looks like the hp increases would be matched by the hp decreases through the 1/4 but only one way to find out...take it to the strip please!!! Exhaust sounds EVIL.

Yes the dyno is correct. There is no power loss down low, the 2 dyno pulls were not started at the exact same mph. If you look at the beginning of the pull versus mph you will notice that run002 starts around 30mph and run004 starts around 40mph. Hope this clears things up.

Yes a tune will make an even bigger difference especially with raised boost pressure. There is gains accross the entire rpm range, I need to post up a dyno sheet with rpm at the bottom so you can see the difference. The stock downpipes are restrictive especially where they kink right after exiting the turbo

Cool please post the rpm dyno. Were the runs in 4 or 5th gear?
