Yosh alpha slip-on?

If i change headers ill be keeping the oem for incase i go back to stock to sell the bike.

My bad I missed the part where you said you were going to go the zx10r headers route.

Yea i discovered that my ramps to load the bike on the truck are to short, thus causing the bike to bottom out om the cat. So i want that thing removed to make it easier plus the weight reduction. Bike is 570lbs stock i think, would be nice to get to close to 500.

they will find out that the bike was flashed and deny the claim

If the ECU is flashed back to a 100% stock image Kawi cannot tell the difference, at the dealership or at the factory level, that the ECU has been modified at all. The image put back into the ECU is a 100% exact digital copy from the image that comes out of the ECU. Meaning every single 1 and every single 0 is in it's exact place where it should be. If you were to wire up to the MCU IC on the PCB, do a raw dump of the internal ROM and did a checksum comparison of the two, they'd be 100% identical between what is pulled from the MCU and the image Kawi has on hand. Again this is something that only Kawi could do at the factory - NOT the dealership. Dealerships do not have the tools, techs or training necessary to do this, let alone comprehend the data contained in the ROM image.

If you have no idea on how electronics works, I will be glad to help you understand it all putting it all in the easiest possible way to understand, but quit spreading bad/false/incomplete information.

Long story short:
1) Only the factory could tell if an ECU was flashed
1a) If the ECU is flashed with a stock image, as pulled out of the stock ECU, it will be a 100% exact digital copy of the image Kawi puts in. Meaning if they dump the ROM and do any sort of checksum comparison or decompile it and review code, everything will be in place and appear normal and they can't tell any difference at all or that the ECU was ever flashed.
1b) If the ECU was sent back to the factory with edited values, then yes, they could detect and see that.
2) A dealership cannot tell if an ECU has been modified unless there is some etching, stickers, etc on the ECU itself or you yourself disclose to them the ECU has been flashed.
2a) A dealership is only going to start poking and prodding if you're bringing the bike in for a major warranty claim (blown motor) - in which case you'd be dumb to bring the bike to them with a flashed ECU only giving them more ammo against you.
2b) A dealerships KDS system works 100% flawlessly and transparently with an ECU flashed with Woolich Racing products (can't speak for others). Woolich works with a local dealership and tests out new ECUs on models the dealership loans them to develop tuning software for (yes, local dealership gives them models to test on). This is done to ensure nothing pops up on their systems to show that the ECU has been modified via software.

Thanks for the detailed explanation. The distinction between what a dealership can check and what the manufacturer could theoretically verify is important and often gets overlooked. That said, I'd still be cautious about saying it's impossible to detect in every case. Different manufacturers may log diagnostic or programming information differently, and procedures can change over time. For routine dealer diagnostics your explanation makes sense, but for warranty claims it's always safest to assume the manufacturer may perform a more thorough investigation if necessary.
