I had a 4" diamond eye downpipe installed recently when the cab was off. Its a two piece downpipe. Is it possible to take it back out with the cab on? It is touching a heat shield and bolt. I need to make some modifications to it. Hopefully this is the reason it sounds like someone is playing a harmonica under the hood. I was thinking it was a fuel line issue but this could be the problem
