Default Installed APR downpipe and high flow cat with stock cat back

<center><img src="http://pictureposter.audiworld.com/5987/100_1244.jpg"></center><p>Nice improvement and I have not installed the stg 2 software yet. Car is louder and has a nice rumble at idle. Under normal load it is almost stock sounding. I do have to take the cat back off again to take off an inch or so because with the step down it pushes it all back a little bit. Fit is great and I am really pleased with the results so far. I just need time to get the reflash! I have my Neuspeed intake on the way as well that should be here thursday. This is such a fun sleeper car.

Default Any perceptible power gain from the DP?

Let us know what your thoughts are on improved performance from the DP both before and after the stage II flash.

Default Steve, Did your car throw a CEL without the stage 2 software being installed ?

I'm gonna purchase the APR downpipe in a couple of weeks but won't update the software until spring.

Thanks, Wes

Default nope, just did the software upgrade last night

and not much of a change. Might take a while for the computer to adjust to the new program.

Default Any additional impressions since you have had time to drive the car and let the software adapt?

Did you get the normal SII file or the beta? How do you feel about the gains from the DP/SII reflash? Also, what are your impressions of the sound? Louder than say, a stock 350z when WOT?

Thanks!

Default It had more of a low tone to it, not as loud as a 350Z

I just got the normal file for my DSG and the gains are nice. Most of the power gain is out of the pipe and not so much the software. I like this setup for this car. Not too much but a difference.
