So when I shift at around 8000, I almost always spit fire, but some times I shoot out sparks? does this happen to anyone els, and what is it? cause the car runs no diff after the sparks nothing changes, is that hot kat rock coming out maybe??

 

What?

 

i think he means is that some of the catalytic convertor flying out the exhaust?

 

could be carbon

 

lucky.. i wish i could sometimes spit some flames(not all the time).. even with my Straight exhaust and tune it just doesnt seem to want to happen ever... eh no big deal tho
