Best shop for diagnosing my exhaust leak??

Jsolo

I had a few small leaks that I took care of after installing the Q300 exhaust on the sedan. When walking around the car I could of sworn there was still a leak present. Couldn't locate it though. After a few hundred miles of driving/heat cycles, the noise is gone. It's now been over 6500 miles since the install and no recurrence.

When you're driving the car, there's so much road/engine noise, i'm really not sure how you can hear an exhaust leak unless it's really obvious.

It's pretty obvious when am next to another car and the sound reflects. It is definitely noticeable, to me at least. I'm guessing all the shops I mentioned should be equally equipped for testing my leaks? I don't want to waste my time and go somewhere where the dude just feels around while the cars at idle and then tells me "your good, no leaks!"
