I have a 2006 Audi A6 4.2 Quattro S Line that i bought a few months ago. Since then i put a custom axle back exhaust on it and have had it tuned by Unitronic. Before the tune was done, the car did 135 mph pretty easy and felt like it wasn't trying. After the tune, I have had the car personally to 167 mph, I was just wondering what kinds of speeds you think the car is capable of when it is maxed out at top speed.
Also do not forget that in aerodynamics F=V^2. So you to get from 135 to 167mph you need 53% more power. I doubt the exhaust would yield anything close to 50%.

135mph does not sound like a lot. You can make it with 3.2 liter motor and skirack. I would not use it for comparison.

That track would have to have one long straight. Maybe a shut down runway.
My old chipped and modded with other power goodies B5 Avant would hit 145-150 mph with enough room on literally a deserted desert highway. There are still some places where you won't see anyother car for 20+ minutes. I would not even come close to that speed nowadays and would only do high speeds on a track to lower the risks.

i'd like to see the pre and post dyno figures as well. Any good quality upgrade should have such diag work available to you. Obviously you didn't spend $550+ on just snake oil. You should at least have the post data available to share, since there's a lot of FUD on the net re: ECU flashes for the 4.2.
