his was a private closed raod
playing for awhile at low gears pulling hard then took it up to 130, saw sparks in the rear view mirror, let off gas coasted down to 70 and still was seeing sparks a little bit, pull off road and look at muffler, tail pipes were faintly glowing inside. I've never seen this happen before (never looked before, but never seen sparks before)
turbo and manifold glowing too, but not very bright.

no noises of any kind, back on road everything seems fine, pulls normal.

the road was kinda bumpey and I do not recall the exhaust hitting the road at all and even coasting to lower speeds still saw sparks coming out.

MTM 1+ and Vmap from Pastore and Stromung turbo back without cats, wastegate turned down 4 turns.
why was I seeing sparks, is there an issue here.

I was gonna say pieces of the cat but you don't have cats. :)

Maybe pieces of the muffler? I have no idea what Stromung uses as a muffler but I'd assume it's high quality...

No idea. :)

All i gots to say is COOL!!!

That is probably carbon in the engine being blown out the exhaust. i would check your Fuel air ratio, you may be running a tad lean.

If your muffler has SS packing, it could be little bits of that being shot out the tailpipe. Sounds like you just got it good and hot and something "cleaned" itself out of the exhaust.
