installed test pipe. raspy noise with stock exhaust.
is it normal to get a more raspy tone with test pipe? my car is completely stock with test pipe and flashpro. increase throttle creates a raspy tone between 3-4k.

60 mm ebay test pipe.
Wasn't sure if a leak was causing the raspy tone cause the exhaust tone used to be deeper with the cat converter. I also didn't get a cel fix code. Did flashpro automatically turned off the secondary 02 sensor? should I remove the secondary O2 or is it fine to leave it in? if I ever decide to return my car to stock, I would like the O2 sensor to be working.

Rasp is normal with just about any test pipe set up. It should be more pronounced under deceleration then acceleration. If you're getting a lot of rasp under heavy throttle then you might have a leak.
If you're running FlashPro that was properly tuned you do not need to do anything (you should not have a CEL) with the secondary O2 sensor (just leave it in).
