Hello everyone, I have kind of waited to last moment to check this but, I am doin a full exhaust on my 97 prelude sh, tri-y headers, full 2.5 inch tubing, 20 inch resonator, no cat, and magniflow muffler. I have heard rumors that running different headers messes with the first 02 sensor, is this true? On the other hand I know that running it catless is going to mess with the secondary 02, but I will eventually be getting the ecu chipped. Anyone know the details about this.
Thanks
Thanks
