Hello! I have a question for those with the Magnaflow 16824 catback exhaust. I have a 2011 hatchback and was wondering how loud is this exhaust in the car? I'm currently running a muffler delete which is way to loud in the car. I have the exhaust routed out the back with dual tips, not just a removed muffler. I'm very interested in the Magnaflow exhaust. I just want to know what the interior sound level is like before I buy. Thanks in advance for your help!!
