Default Problem with Samson pipes, advice needed.
I bought a pair of Samson pipes and the rear pipe will not accept the sensor plug. I am led to believe it is threaded wrong.
After a few emails with Samson technical support they told me to send the pipe to them for inspection.
I was wondering if it would be more cost-effective to just have someone tap new threads in the pipe, or if there are different plugs to buy instead of sending it to Samson?

Thanks,

I would try to identify the thread first, just go to the hardware and buy a couple bolts in metric AND american threads and see what's up!

Agreed, verify the thread size. There have been a couple different O2 sensor bung sizes. Or visually inspect for clean, undamaged threads.

Samson Tech support claimed nothing was wrong it must be dirty threads.
I've twisted enough damned old bolts to now when a brand new part and bolt aint dirty.
So I went to hardware store and after a couple of 18mm bolts barely starting but not fitting I just got a 18mm x1.5 tap and all is perfect now.

So add, $15 dollars to an already expensive set of pipes. I hope they last a couple of seasons.

Thanks guys!

Next time use a thread chaser instead of a tap (or die) because you risk cutting the threads oversized (or undersized if using a die) and that will create bigger problems.

Been chasing threads with taps and dies for more than 40 years with no problems...the only reason "thread chasers" exist is because they are cheaper.

I don't know if I agree with this. Sure the bolt may fit and even feel tight but may leak in certain applications when tapping to a very similar but different thread.

Thanks Next In Line,
I'm looked at some images of "thread chaser" and they look the same as a tap.
Can you educate me on what is the difference? Thanks
