What did you do with your Thunderbird Today?

[XR7-4.6]

Get some late model Mustang GT mufflers or some GT500 take offs. Probably find some cheap if you wanted to test them. I posted a video of mine. Kooks, x pipe, and cats. No drone, good deep rumble.

Those are pretty quiet, my buddy absolutely loved those mufflers and bought several sets for his SCs and they do sound nice for stock mufflers, but it’s probably too much muffling here. GT500 maybe, those essentially are GT mufflers with one of the internal pipes chopped out (in fact that’s a mod people have done)
