I am putting back on the droning exhaust on the 70S. Sounds good outside, inside, not so much. I plan on adding a pair of 12" long resonators. Just before the mufflers or just before the exhaust tips are the only real options for placement. Vibrant supposedly recommends mid way in the vehicle. What say you?
