Best shop for diagnosing my exhaust leak??

which exhaust do you have? and which intake do you have? like Jsolo said some intakes make the woosh noise, and only when you step on it.

Put the car on jack stands and have someone hold the throttle at more than idle. Trace the exhaust under the car to see if you hear or see anything. If not, it's probably your intake.

That's how I did it when I diagnosed it myself. Actually I stuck a rag in both the mufflers to create more pressure in the system and had someone rev it to 3k and felt around the flanges for any air coming out. After I fixed the leaks at the header/tp I really couldn't find any other leaks, but I know I hear one when I'm giving it throttle. I'm figuring the shops are more equipped and have a better way of testing, like a smoke machine or something

I have the stock intakes with fast intentions res. test pipes and catback exhaust.

It's really hard to feel up around the top of the flanges for leaks without completely burning myself so I'm guessing it's probably leaking out of the top of one somewhere since that's the only area I couldn't feel at.
