another downpipe question. (It's on)

[98SilvermistGTP]

What brand DP is it? I have an older RT downpipe that ticked and I wrapped header wrap around the flex and it helped alot.
When you start it up cold do you hear a ticking sound coming from there at all?

no ticking what so ever. I can't even get it to hiss by revving it up in park. Only when its under load when driving can i hear that faint hiss. The DP is from zzp. Also i was curious if there is a right and wrong way to place those gaskets. The one made of sheet metal near the manifold has a side that protrudes out slightly. i put that side towards the dp. and the gasket near the resonator has a thicker side on one part of it. i put that side towards the dp as well. It really stumps me.
