My mods are in my sig. I just had the dp and plog installed about 3 weeks ago. The other day, my car developed an exhaust leak. Thinking the leak was at the joint of the dp and resonator to check it out, I put the car up on the lift and found that where the heat shield is welded to the resonator, at the front tack weld on the passenger side, the resonator is rusted through. I'm stuck between having a straight section of pipe welded in place of the resonator, or a glass pack muffler of some sort. I'm wondering what the loudness difference would be between a straight section of pipe and a glass pack or something else if anyone has any suggestions. I don't want the car too loud and I have factory mufflers. A little louder is OK. A lot louder, isn't. If anyone has any input, it would be appreciated. Thanks!
