Hello everyone, I recently caught the mod bug and figure its time to finally put my new exhaust on my car, I have a dual setup at 3" cat back so far, I am stuck on weather I should just get a test pipe, since my car doesnt need and emissions test anymore. Another reson also why I am not using the original cat is I cant get the bolts out of the cat that held on the flange y for the pipe. ANy suggestions were I should get a new unit from thanks all
