Was hoping for something like this

Damn thats a lot. You better off going Catless and either put back the stocks for emissions/inspection lol

For NY, i was told you can 1 thing not ready, and the catless is not ready so you should pass. I'll find out soon.
I'm not concerned about passing the inspection, i just don't want a CEL, and don't want to tune yet. I'm probably just going with a full Remus cat back anyway but I was thinking of adding a catted downpipe as well.
Got ya. Yea i'd just say go for tune to get the full potential of the downpipe, even if its the OTS tune.
My only issue with a tune was the $3500 extended warranty i purchased 3 weeks ago.
You can always flash back to stock if you gotta take it in.
