While I'm not sure I believe the tubing is 'original' to my car, at least I now the mufflers were replaced. The tubing is fairly rusty, and is 'prebent', so I know it wasn't a muffler shop bend job.

I need to replace the mufflers due to a little buckling issue, but I don't want to have to replace the pipes yet. I can get a caliper on the pipe, but I was wondering what the original size of the tubing was supposed to have been.

I saw many recommendations for 17749 from Dynomax, but that appears to be a 2 1/2" i/o.

Anyone know for sure?

Thanks,
