Well, the lift at the shop was unavailable so no install this weekend. I'll be out of the state next weekend so I think the weekend of the 22nd right before Christmas will probably end up being the date of the install.

In the meantime, on a sound related note. I used a db recorder on my iphone just to gauge the noise level of the Performance exhaust, and these were my results. This was done by holding the iphone at 45 degree angle while bending down to hold it about 2 feet behind the exhaust. Today was about 40 degrees outisde.
