[s-cars] sparks from back of car

[forrest bradshaw]

this 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.
 
 freaking out Forrest afraid to drive car:(
