No idea, 28 in was the max that I could fit in the back right before the muffler cans. From reading this thread from other car forums, 28" seemed like a good start for the rpm range that I was trying to fix. The vibration or "drone" at 2500 - 2900 rpm on the freeway was giving me headaches. I was ready to have them cut and reweld to different lengths if needed but it worked out for my purposes.

Best advice is talk to your muffler shop to be ready to adjust as needed. Someone mentioned using a sleeve and clamp setup to find the best length for your purposes. It will cost a little more to test and tune it but if it's really killing your driving experience then I think it's worth it.

Theoretical calculations are one thing but driving experience is best.
