I used the calculator last night and came up with 27.2' so that's in the range you have. I like the idea of tuning it with a loose cap. Thanks for all the ideas and information.
I drove 90 miles today and was wishing it was already done...
I asked a muffler shop how much he wanted to install this once. This was a place that did custom work. Regular Midas won't do it. He wanted $200 and you needed to give him all the dimensions. I assume he would have welded it in place. He did one for a Dentist on his BMW and it didn't work. Talking with him I found out he just crimp down the end of the resonator and welded it. That's why it didn't work. The sound waves couldn't bounce off the end with it crimped. Needs a flat end.
