Just wanted to post how I went through 3 exhaust in the past week lol. First was muffler delete sounded nice but lots of drone and not much db when getting on it. Then came the shorty corsa resonator and resonator delete in the tail pipes. Much deeper tone still not really loud and you guessed drone. Then came my overpriced as some would say borla atak. Man this thing has the upper raspy loud db range. Also though the least drone of them all. I always thought it was overpriced for a volt on cutback but they did there research on this one.
