    so your o2 sensor is reading off of 1 cylinder?....that should work great

    Stillen or place racing. i believe place racing had a full cat back and teh stillen was an axle back. either way they sound deep and nice. VRS might be your only choice now a days though since the age of the car and the availablity of parts. on the install though

    pathetically poor design, id look into extending the wiring and have an exhaust place put you a bung in past the collector so you can get a true reading, not just one cylinder, it kinda negates the point of a o2 sensor to only be reading one cylinder
