Hey guys just wondering if the Ultimate racing testpipe really is a bolt on testpipe and doesn't set off CEL. Is this true? thanks

 

I have a UR Testpipe, and never got a CEL with it. Had it on with the stock ECU till about 47,000 miles before changing to AEM EMS. If you haven't seen it, it has a small L tube that the secondary o2 screws into removing it from the direct exhaust stream. I'd recommend it if your looking for a test pipe.

 

I have 20k miles on the UR test pipe.. not one CEL from it. It bolts right up.

 

I have it too. Never got CEL.

 

i know several people that are running it and havent gotten a cel with it

i just got mine today in the mail
