Title sums this up. Currently running LTs and have the AEM wideband sensor in the passenger collector. Due to the retardly stringent German noise laws I'm having to reinstall the stock manifolds to quiet the car down (or it won't pass inspection).
That said, where is the best spot to place the sensor? I can't drill into the manifold itself but placing in the y-pipe will be AFTER the front cats.
Need this done so I can retune the car once i place the crappy stock manifolds back on. Car is a H/C car..so it's not going to like this change too much.
