YXZ1000r Stock Exhaust vs GYTR Exhaust test day

[@vincer8691]

The tune makes all the difference.

Sounded good, of course the times would be about the same it’s still getting the same air to fuel mixture without a tune. Guessing a tune should drop like 4-5 tenths?

Without the tune, aftermarket exhaust is pointless. Get it tuned, you'll see good gains.
