See my sig for HP numbers on a mustang dyno. That was with stock headers, off road h-pipe, 2 chamber flowmasters, k&n drop in, no air silencer. around 14* timing.
I just bought the FRPP shorties a few weeks ago and I'm going to be picking up a new X-pipe because my h-pipe looks like crap because it came off another car I had. I'll be doing 3.55's and MGW short through as well and I'll be done for now as far as mods go. I'm not sure my numbers will be much better on the dyno though once I'm done. I then have to look into doing some regular maintence items, such as brakes, struts, etc...
