they should just bolt on but you will still have your main cat hooked up to it though! i'm not sure if it will eliminate the two precats or just the 1st pre-cat!

RE headers have dual outlets. the stock S4 exhaust merges before you even get out of the stock manifold. to use that header, you will NEED custom work.

1. either get a collector and flanges and have it grafted into your stock system, or
2. have a complete system fabricated, or
3. get a header that will bolt up to your system.
