what test pipe wont throw a cell on my 05 z, what is a cell, is it a check engine light? i was liking the intense motorsports and the labree but i hear they throw a cell what ever that means. thanks guys

 

I heard the resonated laboree but i have an 05 and i know they're real picky...

 

It's the year of your car that makes the difference, not the pipes. 03 and early 04, probably no SES light. 04.5+, probably will get a SES light.

 

if you search the exhaust threads, you will learn that the 02 sensor on the 05 is wideband and much more sensitive than prior years. you will also learn that there is a fix called "help" that you can add to your sensor to avoid the light, but since you haven't done that, you erroneously believe the solution is a different pipe. its not.
