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

thanks bro..got any suggestions for a good muffler

[mocha latte cupcake]

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. :goodjob: 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

you can thank nissan for that one. it was a poor design but than again KA's are KA's lol...
