cannot get the second (closer to the front of the car) o2 sensor out on either side, seems like they are stuck pretty hard. did you have a hard time removing any of these??
I used the O2 wrench I posted pics of earlier and I did have to use a LOT of force, a lot. And they finally gave with a bang.
no damage though
its twice as loud but...in normal mode with valve open it growls...very loud...I even hear some burbles not as loud as sports mode.
in sports mode...instead of 3-4 backfires its 7-u backfires and loud, very loud..
wife said in the first 5minutes that the car is faster...
we never drive with windows down, today have our drive was windows down, music off.
on the way back, in normal mode valves closed, windows closed, music on was just normal as before..
love it, anyone who hasn’t modifies the exhaust yet needs to, even if you going to do just the exhaust..go for it. You won’t regret it
How did you figure out how much torque to use when throwing everything back together?
Followed your process of dropping the exhaust and then taking off the sensors. Also got some from pro tips from spdracerut on heating it up with a blow dryer, which made it just fall off.
Did a long drive today.. i let go of the bream in period at around 1400miles
The modes a discrete now, Normal, Normal with Valves open, Sport and Sports Plus are more useable to me know.
I used all of them all day.
Speaking of drone, there is little at 2100 rpm in 7th gear at 75mph...very little but only in Normal mode with valve open and in Sports mode. Turning to Normal mode eliminates it.
Surprising part was that is Sports Plus mode the drone goes away too, in fact sports plus was great at high speed cruising and quieter than Sports mode

Gotta put everything back together today
For the headers its 18lbft, for the rest - its all the way like the bolts between the turbo and cats/headers.
Before and after mods in Sport Mode. Consistent with the changes in Normal mode. With the exhaust mods, you have the better defined pulses. I noticed the trend of the increasing dB with the freq of the peaks, same as in Normal. Interesting thing is down around 20hz-ish, the stock exhaust has a bit of a bump which is gone with the exhaust mods. Around 180hz-ish, there's more noise level with the exhaust mods. It would be fun to see what it looks like in-cabin when you floor it
