It all about how careful the mechanic taking that out , unclip the o2 sensor when taking the oem header out and then spray wd40 on it, and then slowly take them apart. That how we did it, same with my old is350 with ppe header never had any problem with taking them aparts. If u just trying to take them out while they are still connecting with the engine bay that is going tripped them.

Tone OK as everyone now knows you will no longer here that secondary intake open up which adds to tone and note of exhaust, that combined with JoeZ PTS exhaust/intake with factory headers made fanatic sound especially when there is no drone present in higher rpm levels when your going throw the gears in manual sport mode it has distinctive note a kind of sing song up and down sound that was glorious. The tone of exhaust note has changed it know longer sounds same its different not in bad way you can here more of exhaust note coming throw headers and less of intake sound I attribute this to two things no longer hearing the secondary open up and drone I will discuss drone next.
Drone there is less drone especially when driving on flat road under normal driving condition now if your driving up incline or when and in that 50mph to 65mph between 1800 to 2500 rpm range in 8th gear some drone will appear but overall less drone
Sound level here the funny thing its actually quieter the guys at AFterFX had driven car prior to PPE headers install and took F for test drive after PPE/ECT Hiflow cats were installed and they were surprise that the car was actually quieter now these were my findings as well. Now when driving in normal to slightly sporty way the car is retentively quit when at 60% to 70% throttle or driving in more aggressive manner and at WOT yes the car is louder then before it sounds just beastly.
Whats also interesting is in-cab sound level is less, at first I though the car was not loud at all but when my friend took it for ride and I heard him come back I was like WOW my F sounds great very nice tone and note. So less in cabin sound slightly more noise on outside. Another way I can tell that there less internal sound once again using my unscientific measurements is based on my audio sound level. I use to set at certain level when communty home, now I know longer have to keep volume at previous higher sound level in order to hear music comfortably.
Aggressiveness yes when I'm pushing F especially in sport manual mode exhaust note is fantastic and yes it is louder than before
Once again these are my opinion's and are subjective and are not based on any sound level equipment just my observation and personnel taste.

I agree with you, it seems bizarre, but I believe my PPE headers actually made the car quieter beliw 2500rpms or so. Anything above that and the car sounds like a monster 
Oh yeah, no cats on my car.

Hey KJH this is wear it gets interesting and I was surprised with results now my findings are subjective and unscientific since I didn't use decibel meter to take any measurement prior to PPE headers install but what I'll do is break it down to 4 areas Tone, Drone, Sound Level, and aggressiveness so here it go's.

Aggressiveness yes when I'm pushing F especially in sport manual mode exhaust note is fantastic and yes it is louder than before
