does anyone have dynos before and after their exhaust? preferably someone who ended up getting the GMPP or some other 2.25 piping and someone else that got magnaflow or other 2.5 piping

 

full 2.5 in pipe w/ injen intake gave me 148hp on a mustang dyno

 

with 2.25in pipe borla universal muffler, and injen intake I got 146hp on a dynojet but it was in 2nd gear. and 135w torque

 

It's $100 at one of the local speed shops for dyno setup and 2 pulls. I'm about to do my exhaust and while I'd love to do before and after dynos, I really can't justify spending 200 junior bacon cheeseburgers just to find out what kind of power said exhaust gave me

 

tell them to stop being jewish and do a before and after
