Changed exhaust engine starts to die after revving sometimes?

[nsh95]

I put baffles in my straight piped Y-style exhaust to dampen noise some however after I did this and revved on the engine some acted like it didn't like something and began to fall under idle until i revved back up then it will run fine.. Any ideas? Car is tuned for straight pipes..

Side note; revving was on the two step or launch control, my buddy said that just sometimes happens when you let off throttle immediately after hitting the two step?

Lol I guess next time I'll put my questions in http://www.audizine.com/forum/showth...oo-dumb-to-ask ....
Ended up reinstalling the baffles, runs with them fine, does try to provoke the car to missfire if you hit the launch control and let totally out of throttle, apart from that great remedy for loud ass pipes.
