Best shop for diagnosing my exhaust leak??

bmarcinczyk14

So I recently got my new exhaust installed and I hear a annoying leak when I step on the gas, almost sounds like a turbo woosh. I've lifted the car and found a couple leaks at my header/tp connection, put some high temp rtv on the gaskets and fixed those leaks and after that I couldn't find anymore, but I still hear the woosh when I step on the gas. What shop out of like Midas, Merlins, Firestone, CarX, ect. would you guys say is the best equipped to diagnose my leak? I know the obvious decision should be an actual exhaust shop, but all the ones around me seem really shaddy.
