The exhaust was purchasd used so it was broken in already. Sorry for the dumb question but is there any way to revert? Or am I just talking jibberish and it's just me that my exhaust sounds different?

just to confirm -- you threw on an axle back, and did the reset, and now it sounds different? there's unfortunately no way to revert back to the previous sound. likely though -- the change in tone didn't have anything to do with the ecu reset. resetting just allows the car to relearn your habits via throttle response. it doesn't change your air:fuel significantly. this whole mumbo jumbo about the car potentially running stock after mods is a bit misleading, in my opinion. More air requires more fuel, which as a byproduct, gives more power.

the change in tone is likely just your exhaust adjusting to your particular car after installation. no correlation in tone to resetting your ecu.

Thanks for the Tip!!
I was told by my mechanic to un-hook the battery and touch positive and negative together and then turn on and leave around 1500 rpm for a second before you start driving.. but this definitely worked!! My car was acting up A LOT after I installed my new Takeda Intake and Muffler Delete w/ Custom Pipes Exhaust Mods.. Thanks A lot!!

I disconnect my battery for storage and start it a few times during the winter on the warmer days and run my ac etc move the tires to sit on a dif position... It also sounds weak with a cold start. You gotta go for a rip in it after to relearn to be aggressive after your reset. Once the engine hits proper operating temp go give it a shift for a bit and come home safe tmrw start it and it should start loud... Works on mine.

I added a k&n intake and did the ecu reset and did not notice a difference with a tank of gas so I tried the same thing again. Wow it worked great. I may have missed the timing on the 7 second and 1 second will cancel the whole think. My answer would b to try again.
