I was only able to put 10 miles on it today but it wasn't smoking as bad with muffler off. Makes zero sense but whatever.
Is it bad for me to just run open dp and have no exhaust after the ypipe where cutout is?

Its burning oil. The reason you dont see it from the cut out is the exhaust is still hot. By the time it reaches the mufflers and tail pies, the exhaust has cooled and slowed down quite a bit
They were hit with plenty of boost not long after break in. If the rings were that wasted the engine would have a quart of oil blowing out of the breathers every pass. Rings (particularly second compression) have to be totally wasted to cause a smoking issue. The rings were file fitted and the bores were clean and correctly finished for the rings. It only takes a little oil to make a lot of smoke.Is the engine using oil? Better hit the rings with boost before its too late.
