Water in my Exhaust

[IKillDeer]

I just installed the Roush Exhaust this weekend. When I unhooked my stock exhaust there was a lot of water that came out of the resinator pipe. I noticed driving home last night after my truck had been sitting for about an hour the new exhaust was making a noise that the best I can explain sounded like the noise you get from an old 4 barrel when you first floor the gas pedal. That sound came when I would barely push the throttle down and only last for a split second, I could really feel the vibration in my gas pedal, very annoying. By the time I got home it wasn't as bad. Just wondering if the Roush exhaust was creatting too much condensation and causing that noise. Has anyone else had this propblem?

Condensation and if it has no place to drain eg hole in muffler then you get build up which will burn off after a few highway miles at speed BUT will rust out the insides even on a ss muffler over time...

Condensation is normal nothing to worry about, just hope your exhaust material is the 304 grade , not 409 or mild steel.
