I am in Tennessee and not worried at all about passing marta next year.I have a group buy priced, never installed MAPerformance DP with vibrant cat but no resonator that I am going to have to sell after reading this thread.
After reading on here, I can't have it throwing a CEL, and it sounds like everyone on here with spacers can't get them to work longterm.
In my state, we have to pass full OBD readiness every year, so I can't use a tune that suppresses it.
Sad panda. Stupid Tennessee.
Mine has thrown a code but it is very rare, 4 or 5 time now.
I can go over a week without seeing the code.
When I feel like it I will put the smaller spacer in and see if it helps.
You won't have a problem with TN marta if you have VCDS or OBD11 or JB4 to clear the code when/if it does pop up.
If it does pop a code and you don't have a way to clear it. hit me up... I will clear it for you.
I am in Nashville also...
