Great DIY Don. I did this install yesterday and it went really well. The key to the install going smoothe was having an impact wrench for the front bolts.
I have the same issue. It is due to the clearance with the mid pipe on the cross brace. I plan to order new exhaust hangers and that should help. I don't get the noise often but when I do it is definetly noticable.
tl;dr: Bend the center, shorter cross member down to increase clearance or use header tape so it's not hitting metal-to-metal. I don't think exhaust hangers will fix the problem.
Do have a question for you using the invidia mids;
I have the PPE headers (catless) F-sport catback, and F-sport intake. I know the mids will pretty much add no HP gain but at about 78-80mph I get a pretty loud drone. Does the invidia cut down on that, make more raspy perhaps etc?
Car is loud as hell as is, just looking to kill the drone a bit for long trips.

The invida will make your car much much LOUDER. If your looking to kill drone, this mod is not for you. Neither is the PPE headers for that matter
Btw the Fsport exhaust is an axle back, not a catback.
If it was a catback, you would already have different midpipes
Ah yes that was a mistype on my part, being loud isnt the issue just curious if the mids would change the "tone" to something a bit more raspy but isnt issue untill 80mph mark, drops off at about 90mph and is fine.
How do you remove the 02 sensors from the midpipes without the wires twisting all up? Is their a way to remove the sensor from the bolt so it wont twist?
1. Not a ton of work but w jackstands and a helping hand it can be done.
2. No CEL
3. The o2 sensor is in a PIA location.
4. Yes you need to remove 2.
Check out the thread i made for when I installed it. I love mine w just the stock axle back. A nice subtle change. Let me know if you had the same issue as me. My pipes were banging on the lower brace bar. I ended up replacing the spring bolts w fixed bolts and used washers to move my brace bar lower, giving me more clearance. I purchased my pipes new.
installing invidia mids soon which I am buying used from another cl member. i want to replace the gaskets and will probably stop by o'reillys later. are they just called crush gaskets for the midpipe? and how many gaskets will i need?
