^^ I think I paid 200 plus shipping for my ceramic coated headers, with gaskets too. You may need to buy new bolts though and also make sure you are getting a tune since your removing the cats. I ran my ebay headers, the discovery automotive race tune, stock center sections and supersprint race muffler and loved every minute of that sound. That car screamed!!

 

I have a set of ebay headers that might be for sale as my car didn't pass emissions so I went back to stock.

Let me know if you might be interested. They fit perfectly and I had them on the car for about 1 year or 6k miles.

 

had em on my 2002 smg m3.
fit was excellent and the power increase was worth the money.

 

I've had mine for years. Stick with JVT-R (I think they might have stopped production). Mine fit fine, just a b!tch to install them. Nice gains, no limp mode, overall very happy with them. Would recommend.

 

I looked into this when I first got my E46 M3 and I believe most people recommended the brand JVT.

Hopefully you can find them. Good luck.
