Did any of u throw a check engine light while using them? And did u have any problems at all?....Im installing mine on sunday and this guy from work wont stop droning on about how test pipes made his o2 sensors go bad on his rx8 :

i'd love to hear what they sound like if anyone has a sound clip? im too anxious to wait till sunday lol

 

i know this is kinda offtopic but does any one have any sound clips of a Z with resonated test pipes w/ stock exhuast ive been looking for sound clips but cant find anything

 

check the Diy forum for the fix on the cel.

 

u kabob!
