So it's 2017 and I need a header for my 2013 GE8. I had to remove my Weapon R header due to issues, I replaced it with the T1R. I wish I purchased the SuperCircuit header, I found out about it too late. Still might buy it, just to test it out. Most headers by now are discontinued from my search. There are a few still floating around in vendors stock.

This is what is still available that I can find (all are cat-less, all require a CEL Eliminator):

1. SuperCircuit w/o EGR - $285 USD shipped - So beautiful.





2. T1R - $358 USD Shipped - Definitely a close second, bought from A&J Racing.





3. Weapon R w/ mid-pipe - ~$300 USD - I do not recommend this, I had issues with mine and replaced it with a T1R.

 

The SuperCircuit and T1R only remove the front cat. The Weapon R removes both front and rear cats.

You will need a O2 sensor relocator/ CEL Eliminator for all three headers. These can be found on Amazon (everything can be found on Amazon).






The SuperCircuit w/o EGR requires a EGR Block-Off Plate to cover up the EGR port. The EGR has no effect at idle and wide open throttle (WOT), removing it will not increase performance. In fact, you will likely lose MPGs on a daily driver. The purpose of removing the EGR is to clean up the engine bay on track-cars. These are a dime a dozen:

 

Good looking out De36!!

 

What issues did you run into with your weapon r headers?

wow, that is pretty bad........and the response from weapon r is also pretty bad......never going to buy from those guys again.

 

They Supercircuit seem to have a newer version of the GE header that looks as though the primary 02 sensor is already raised and it also has brackets to attach the stock heat shield if one so desires.



Just sent them a message about the cost to include shipping.
