Hey man, it's not stripped I don't believe. The OEM header had a metal outer cover that makes the washer flush. You just need to add a thick washer spacer in between the O2 and the header and the rattle is fixed

Safe way for all aftermarket headers?

No no no, you use ANTISIEZE on the O2 sensor threads!


Unless you like having to heat the O2 sensor and header up to red hot to remove the O2 sensor in the future...

yeah should be fine, the stock header had a huge heat manifold that made the washer snug

+1 on that ,just don't get any on the sensor tips.

and run a M18x1.5 thread tap/chaser through the o2 bungs to clean them up so sensors screw in easy

Make sure you get the blue label. Avoid green and red, which would make it a permit seize.

NO. Do not use thread locker! Antisieze is what you need.


If the threads in the header or O2 sensor are messed up, chase the threads. You can use a thread file too if needed.

I'll find out later this week as I plan on removing my headers.

Apologies if this has been asked before, but I know it's highly recommended to replace the gaskets between the header and the engine and overpipe, but I've read many recommend unbolting the front pipe to the mid pipe to maneuver the overpipe away from the header to allow it's removal.

My question is, should the gasket be replaced between the mid pipe and front pipe?

Also, apologies if I've gotten my exhaust terminology incorrect.

i installed my ofh without loosening or removing anything other than header connections.

however we a right hand drive so might be some clearance issues on LHD car dont know

the midpipe/frontpipe gasket is a doughnut and can be re-used if you do loosen it

see the basic bolt on mods link below its got diagrams and tips on installing header

I thought it was just my car? I know I have a shitty gasket between the mid-pipe and axleback, I figured it just got worse over time..... maybe I didn't have to order new gaskets after all and it's jut the tune?

Ah well, the axleback gasket and the donut gasket are getting changed out anyway!
