good exaust set up

I have ordered FRPP Shorty headers, BBK x-pipe w/cats and magnaflow cat-back

I had stock exhaust with a dynomax catback that I am replacing. It sounded good. Do you think I'll feel any power difference in the seat of my pants? Also, how different will it sound? I liked the way the dynomax system sounded with the stock H pipe. How will the x change things? I like a deep throaty big block sound...
 
im running bbk shorties a bbk catted x pipe and dynomax race bullets through 2 1/2 inch pipe and i love the sound, but if you want deep and throaty, you dont want an x pipe, thats gonna make it raspy and almost nascarish sounding, an h pipe will give you the deeper sound. and youll probably feel a little more pull
 
I agree with most of what you said. His exhaust will be somewhat raspy, however most comparisons have shown more horsepower results with the X-pipe. I run Bassani equal length shorties with bassani O/R X-pipes and Magnaflow cat-backs and definitely noticed an increase in power. I even saw a boost in power when I swapped my Magnaflow X-pipe w/cats and went with the Bassani O/R X.
