I was just wondering about if anyone here ever had problems with their interiors rattling because they have dumps. I ask this because I have MAC LT's, ProChamber, and MAC Cat-back, and when I just took off the tips, which left the pipes hung a little over the axle, and when I did this, it shook and rattled my whole car. It was just too much for a daily driver. I was wondering if there is a difference in tone or rattling i cut the pipes and weld on turn-downs? I also have p&p heads, and cams which made a difference in my exhaust tone.
