    Did you add the resonators too or no?

    They just look big compared to the tiny 14" magnaflows. They're about the same size as stock panther mufflers, maybe a little smaller.

    Yes the resonators were added after the magnaflows were too loud. I have no idea how the system would sound if i removed them. I may or may not eventually find out. As of now I'm pretty happy with it.

    so both at once. I was wondering if the resonators made a significant difference on their own. I may give it a go. I'm tired of the drone on the Towncar, and swapping the straight piece behind the axle for a resonator would be simple enough to do. I have a set of Magnaflows under the car now, and I think they are the 20" version but I'd have to actually look. Its been so long since I really looked at what was under there, I just don't remember.

    Resonators made the car about 1 to 1.5 decibels quieter both outside and inside the car, from 10 feet away out the back of the car measured on an app on my phone...so they do make a difference, just don't expect them to work miracles. They cut out the harshness of the exhaust note, make it more mellow. If you have the 20" magnaflows perhaps these would be just enough to make it nicer. You can see how you like my setup at scottfest

    Mostly I'm looking to kill the drone. There is one speed where it feels like my brain is rattling inside my skull, its fine otherwise. Sound deadening material in the trunk helped but if I could tame that noisy spot I'd be happy.

    Yes, I had the BBK Shorty and Mustang cat'd H-pipe set up. If like Kishy; you're not driving it in the winter with salt and such, your setup should work for a while. A few months before I parked my CV, the cats rotted off the H-pipe. Could be something to look out for. Otherwise, those Dynomax muffs were great on the lopo.

    If I didn't install cutouts, my Mom would have hated the CV though
