I'm looking at buying the Akra y-pipe. Are you able to screw in the 02 sensor in the Akra y-pipe, or do you have to get used to an engine code going off once installed?
Yes, you can screw in the sensor. If your running a PC or any other FI module, just leave the screw in the Y pipe, the stock 02 sensor will screw with the PC mapping so leave the 02 sensor out.....
I have the Dobeck Fastcard, no 02 sensor, and Akra Y pipe with GYTR slip ons, runs great...also running forum member MRGRN's custom CF heat shield, screws right into Akra or stock Y pipe....
all the stock 02 sensor does is lean the mixture out for emissions....if you take it out even with no PC it will be fine, if you plan on putting a FI module soon, just leave the screw in there, cause it's already safety wired
