Kleeman headers Arrived W202 W208 55's
Well, than the gains should be even bigger!!!!
Coat them only if you care about their appearance, after several thousand miles they will turn into "rainbow".
Have fun!!!
God! I miss playing with cars................
I have those headers and I had Swain coat them with thier header coating. It made a tremendous difference in header temps, much lower temps transmitted to the engine bay.
They are difficult to fit. Also I would take a carbide tip grinder or stone to smooth out the inside where you will find some rough welds.
I also got my hands on some METAL CATS to run. But before the cats check into putting an "X" pipe in place to help scavange the exhaust flow.
To get the ECU to work properly you will need to extend the rear pair of O2 sensors and weld in two fittings for them.
I don't know how well they work with the 5.5L motor but they worked very well on my C43 which pulled as hard as a 5.5L motor for the last 1000 rpm or so.

I figured the Y-pipe was basically doing the same thing which i have installed right there after the cats. I have noticed a lovely perfromance increase pre-headers install. I'll PM you!

Would also recommend coating with this product http://www.zircotec.com/ which is probably the best solution around (not cheap) but it really works
