I'm looking for a catted cat back because I am trying to get a full catted setup, from the downpipe to the catback so i can pass smog....the only issue is since im Stage 2, idk if i can cause i heard the smog ppl hook up a computer to your ecu and it gives off different numbers so it doesnt matter if your catted or not, you still wont pass. Any input or corrections would be mostly appreciated...Get at me for the catted cat back also...need asap.

 

you only need stock dp to pass smog.. the catback is mostly for visual.. as for the plugging the computer into the car.. I think that's jus to check the sensors etc.. you can only have 2 or 3 that dont work..

 

oh ok. Well if thats the case, im keeping my helix
