i would still use a hotdog, big long fella, but fit it in the middle of the car, then fit a decent straight thru muffler at the back
still gives you a good note, very little restriction but a lovely "Note",,, not a bark
one of the beautys of this is that the hotdog will take a lot of the bite out of the noise & the burn, making the rear muffler last longer & sound nicer, & with no BARK

easy-peasy
& any decent straight thru or "S" bend muffler of the right size will be finew, just go to your local exhaust shop & ask what they have
