Nature of flex pipes. The exhaust will accelerate when it comes up on any sort of ribbed/rough surface. That will lead to whistling.

I thought it was the flex too. I have a 97 GTP with headers and have no whistling. I know ones a V-6 and a V-8 but the design is basically the same except they do not put a flex pipe on the x-over. I said in an earlier post that I thought the flex should have went on the end/collector part of the headers. I bet that will solve the problem. I am just going to wrap mine until there is a permanemt fix for it.

am I the only one that sees this as a problem?
The whole purpose of the flex is to prevent binding in the exhaust as the engine torques. So what's flexing if the rear manifold and the rest of the exhaust are all one solid mount? I might be overreacting as the stock downpipe on my car doesn't have flex but that to me sounds like a leak waiting to happen.
