AudiForums.com - exhaust installed need some pointers

I am brand new to these forums so take it easy on me.

But my issue is My exhaust I have a 98 audi A6 2.8 and i am running Remus sport label flow through type exhaust. I just completed it deleted all the resonators, and now I'm running true dual's. My problem is that the exhaust is really raspy, when its cold. But when the car is warmed up and the exhaust the car sounds awesome and there is hardly no rasp. I was thinking about buying some small resonators or I was thinking my flex pipes up front are going out. Because i hear a small leak.
My thoughts are to install a X pipe and just delete the flex pipes. But everyone has told me True Dual's are the best...

any trouble shooting would be great I was thinking about a X pipe, but the exhaust was already about 700 in all
