Hey guys,

Have a set of MINT Agency Power headers for sale! Changing up the set up for spring! Wanted to put this post up as a feeler as the headers are still on the car! Removal of the headers will be done by Rocco@RMP motors, install for potential buyer can be arranged (at buyers expense) at time of removal if buyer requests in advance (Rocco offers the best rates IMO)

Headers have been used just shy of a yr barely as I mainly drive my car on weekends, perfect hassle free fitament! And a big gain in power over stock! I will try to dyno the car with these headers before they are removed!!

Direct bolt on, no cutting welding necessary! Has Egt bung welded in already!

Thanks for looking

From Agency Powers website:

"As one of the finest automobiles delivered from BMW, the E46 M3 has lived up to all its expectations as a true performance car. As enthusiasts try to squeeze any additional horsepower out of the inline 6 power plant, Agency Power has made it much easier with the release of their performance racing headers. The 321 stainless steel headers are a direct bolt on in replacement of your factory headers. The headers replace the factory catpipes and are to be used for racing applications. The headers have thick flanges and amazing welds to insure longevity and strength compared to the competition. Each pair of headers includes the necessary oxygen sensor bungs. In addition to improving upon horsepower, the headers will also help achieve low end torque for the “off the line” power feeling."

does you check engine light come on? do you have to replace the cats?

If you don't weld race cats in section 1, CEL light will come on as you lose both pre-cats that are on stock headers.
Unless you Shark (Sharq?) it, or install any of the NA Tune ECU reprogram.

Getting Supersprint Headers installed this thursday and had to purchase 2X 2.25inch Cell 200 race cats as I did not want to do a ECU upgrade.

I run the Shark injector software, w/o cats so I have no CEL lights at all.

When I FIRST installed the headers w/o software I did get a CEL light. So YES unless you run racecats or get some form of software you will get a CEL light.

Also, headers were sold last yr guys!
