I just took it out, steering is all good, I dont think I have leaks, it's weird, it sounds like the sound ppffff when I accelerate, but when I get off it goes away, even on decel. When I get under the car, under idle, I feel no leaks. Is it possible the headers increased the sound of my rotofab? I would think if it was a leak, I would hear it on decel. I haven't gotten on it, and probably wont untill I get a tune but so far no check engine light, strange, I'm sure it will come on eventually. Maybe because I'm babying it.

You know I’d have to say if you had a leak with the way the stock NPP ‘talks’ on decel, you’d think that same type of sound would mimic itself.

Since your exhaust is flowing better, you might be hearing the RF!
