Just did the install and took about 90 minutes. Hardest part of the job is the rear muffler hangers. Definitely get yourself an exhaust hanger tool ($30 at Advance) to make the job easier. Anyways I love the sound. Not obnoxious at idle and fairly tame unless you get on it. I immediately went on a 5 hour road trip to Pittsburgh and I love it on the highway. No drone at all. Cruising 75-85 around 1500-2000rpm is chill. I am very pleased with this system @[email protected]
