If I do decide to run Test Pipes on my Z will they cause flames to shoot out while driving? I had this happen on my previous 1.8t when i removed that cat and wasnt a fan of it that much. Will this do the same thing?

 

i have only heard of one person having this occur to him, so i would say with 99.9% confidence that u wont have flames shooting out.

 

I think it either takes an sprayer or you have to run reallly rich and no cat (I think).

 

yeah, running rich is what normally causes that to happen... unburnt fuel is reignited causing the flames.
