. Very fewiles have been put on the car since doing this and I lived with it. Now I'm driving it more and the tinny noise bothers me. I also feel like the insides of the mufflers may be blocking the exhaust and hurting the power. Has anyone had this occur? I had a 74 Malibu that had a collapsed muffler once and it completely killed...Blew up mufflers. 70 440 HP 300
