Although it’s not shown here on a dyno graph we also tested a better cat-back exhaust system for the V-6 Mustang and found an unbelievable 10 horsepower at the rear wheels from about 4000 rpm up.

RE: HP gains with Flowmaster
Yea if you added on only a catback system 10hp gain seems fairly accuarate, you would of gotten more had you bought a true flow dual exhaust system, x or h pipe with cats. Oh don't forget 210 is the hp off the flywheel, your car is actually running at about 170 rear wheel hp. Ford always releases their hp rating on the flywheel instead of giving the real hp rating which is your rear wheel hp. You loose hp due to your car weight, your pulley system, your gears in your drive train and your rear wheel differential.

170!?!? i knew there was some negation cause of all that stuff but losing that much horsepower is depressing

170 is about 19% loss... which is actually would you should expect with an automatic...

Why is the automatic significantly less powerful? I figured a manual would have an edge, but 20%?
