Test Pipe.....worth the risk or not
I spoke to the guys at eurocode tuning about going to their shop for an APR chip and a test pipe install. I have a 07 A4 S-Line Cabriolet with quattro. I did not realize that the test pipe replaces the cat. I am concerned that the dealer will see the cat missing during routine service and make it an issue. I am less concerned about te chip. I have 600 miles on the car. Any one here in the WLA area that has a feel for a service department that would be cool with the test pipe. The extra HP from both would sure be nice on this car

That's not even remotely true in the case of a TP
By installing a TP, you've modified the vehicle in a way that makes it illegal to drive on public roads.
It makes it illegal to register to drive on public roads.
The MM Act wouldn't apply.
Now, add to that fact that in order to install and run an illegal TP and not have a MIL, you must be running aftermarket software for the ECU.
Will every dealer make instant note of it on the spot? No. (But they probably should)
They are going to want your business, but they are not going to run a foul of AoA or the DPS to keep it.
If you have a TP and have engine/exhaust/ anything that could even be remotely related to those then you're going to be denied warranty service (at the very least).
That's just the way it is.
TPs are illegal. If you want to run one, then that's on you.
Mod away, but be informed and mod smart.
If the extra performance gained from a TP is worth breaking the law to you, then go ahead.
But, if you do, you assume the possible financial and legal liabilities associated with that risk.
Oh yeah, and don't forget... your insurance company and finance company might not be very happy with you either.

Re: Test Pipe.....worth the risk or not
I have mine TP installed and APR chipped @ ecodetuning. Now my car has only 2.2k, so it's not time for 5k first service yet. I do not think a TP will void the oil change service. If dealer blames on the TP that cause other issue within the car, they will have to prove it.
