Buying defoulers for Megan Racing test pipes. Does anyone know if these would work?

 

let me know also.if they do....

 

If by work you mean trick the ecu into not throwing a code then they might, no guarantee tho. Sometimes they do sometimes they don't... bigger problem is that even without a code your ECU can't compensate for the test pipes and deleting the cats so its not going to run that great. You really need an Uprev tune to get it running right, take care of the codes, and make a bunch more power
