What mufflers for 340

That's one beautiful car and sounds lovely! Literally love everything about it, especially the cleanness of the trim. I've been having a hell of a time to get my lower back window portion to sit flat, most likely due to the fact that the vinyl was put on without removing the window and it's probably a little warped from sitting in the trunk for the past 5 years (from PO).
Thanks,
I've owned this car since 1981. This is the second vinyl roof I had put on. The first one was put on by a body shop guy and he didn't use the correct glue so it started lifting on me within the first year. I put up with it for about 10 years before I had a shop that specialized in vinyl tops put it on. I suspect that if I had done it myself it would have been a disaster.
