Recently I was racing a buddy of mine(legally at a sanctioned event of course ) he has a V6 mustang, the reason that matters is that he was pretty far behind me by the time I was shifting into third. He says when I cracked 3rd sparks shot out of my exhuast. I said are you sure it was sparks and not flames? Because flames are normal(cue rev to 7k followed by a few flames) Nope, it didn't look like that, it looked like sparks. Then, later on at a legally santioned drifiting event, someone else told me I shot sparks hitting third. Any ideas?

There probably wasn't enough excess fuel for it to make flames, and instead made a small spark. :shrug:

oops

sounds like your cat is breaking up. i drove some guys ford probe that did this, it would shoot flaming pieces of catalytic converter out the back

yeah thats what it sounds like to me too, its actually little pieces of cat, burning up out of the exhaust.

Well, that'd be all well and good if I didn't have a RB pre-silencer, header, and cat-back. Thanks for the help so far, but any other ideas?

muffler packing being blown out.

yeah stainless wool coming out maybe

that's why RB exhaust uses ceramic packing. other packings just can't take the heat of rotaries and just burn up.
