My car is going over to Kooks Headers on Nov,11. Here is the deal. They are going to remove the factory exhaust right in front of the secondary cats. With the secondary cats gone they are going to custom make a 304 stainless system that slip joints on with 3" stainless band clamps. Both 2.5" ID pipes will run on the drivers side of the differential to avoid removing the protective shielding around the fuel pump. There will be two round tube racing mufflers made by Kooks that look just like the Magnaflow 14160's. installed using my factory tips. There will also be another slip joint to allow ease of removal and installation. The system will have no welds and is all mandrel bent using 304 stainless, mufflers are also polished 304. This is what is planned, if anyone else is interested in this set-up just the way it is let me know and I will see if they will make another system or save the file. Price should be between 700-800. I don't know if they will make another system or just say it isn't worth while, I guess it all depends on how much time the actual system takes to fabricate on my car.
