75 MPH? Lol maybe with 4.4 or shorter FD. Stock you're at about 89-92 at the top of 3rd, depending on tire size.
Just saying..

 

my speed is entirely irrelevant to the issue... i was just trying to see if anyone thought i should be worried lol.

 

Just claim that you were in Mexico, that's what all the GTR guys do when they brag about street racing online You can even post pics/vids of you clearly driving in 'Merica, but it's ok. Because Mexico.

Anyway, it's probably the packing from your muffler.

 

I bought it from yall! lol... ever heard of it happening? (honestly im good, i like it, good sound, and even if i blow my packing out the silencers still work the same lol.)

 

Wide Open Throttle is high pressure LOW vacuume and on decell its the opposite low pressure High vacuume. Combonation with the sudden lean mix ur probably heating the carbon in the engine enough to where its burning off and going out the exhaust pipe. U can also check the cat and the mufflers so see if they are falling apart as well... my 2cents...

 

I keep seeing the fuel thing, if it was fuel it would be flames yes? Just a shower of sparks lol

 

Are you sure it is just sparks? Are you behind the car? When it happened in my car, all I can see from my mirrors are sparks from the flames but my buddies said there was a huge flame causing the sparks, the flame just wasn't high enough to be in my mirrors.

I said happened because it doesn't occur anymore since I got my Flashpro and tuned it.

Either way, whatever it is is not going to damage anything important.

 

Just called Mike, (The Drifter on here) and he said it was just sparks, no flames at all, but he made a good point... i run with my silencers most the time... i took em out for the meet after bout 3 weeks of em being in. There was kind of a ridge of crap built up behind the silencers... my bet is i was blowing that buildup out.

 

That could be it

 

i threw an emissions code after 5000 miles since i added the test pipe... so it clicked in my head. The invidia TP i have has some sort of mesh thing before the o2 bung, its just a small about the diameter of a quarter with what looks like a little bit of cat material. and considering my header is ceramic coated, im betting all the heat starts building right at the test pipe. im betting i melted it. gonna have to pull it off in a few days to see.
