any chance of getting a video of this? Is it doing it at idle? Any metalic sounds coming from the engine? vibration? done any recent engine work? More info needed...

No recent engine work other than a tranny rebuild in oct. No weird engine sounds or vibrations runs good except the cold idle choppy loop... Sadly no video either
I will let someone else run it and I will watch it I guess.
O ya I wasn't on the brakes, about half through the run doing like 90ish.

I have noticed this before with power adder cars when under extreme load at upper RPM. More than once the sparks preceded heads gasket failure. I thought they may be due to portions of the gasket sealing ring being eroded and passed out the exhaust. Just my own guess.

It's way too premature to draw any conclusions....I have seen sparks out the exhaust for many reasons - burning carbon off the exhaust manifolds, muffler material leeting loose, old air cleaners flaking into the intake, etc., etc. If you're not getting ping or knock retard I doubt that you are harming the pistons.

Are you sure its sparks coming out of the exhaust? Ive heard of people with gutted/no cats and a free flowing exhaust shoot flames out their tailpipes on shifts. If I remember, the consensus was that is was the unburnt fuel from between shifts being ignited. Ill try and find the thread.
Edit: Heres one of the threads about it

Id say have someone record it on video and see whats really happening.

I asked again and they arn't too bright lol, they said they were orange though and fell on the ground. I'm wondering more of a bottoming out of the exhaust isse cuz mine hangs hella low and i've already ripped it off once on a speed bump... plus it was on the incline of a small hill.
