Like PSJ asked is that fwhp or rwhp?644 fwhp through my actual lid & air filter & MAC's and 2.5" mufflers...rear was north of 500, but I don't like chassis dyno figures due to too much variation and set-up differences...the 325/50/15 DR's strapped that tight cost over 30 rhwp as tested vs. a 235/50 regular radial, and so on. Not being secretive, but there are too many "tricks" if you just wanted to show a big number.
Take care. Dave

LT's are not on my shopping list...the MAC's thr. the 2.5" mufflers made 4 hp MORE than 1.75-1.875" stepped headers run open with extensions. Torque was down 10, but well below where I run the car. Long tubes tend to help down low and shorter headers up top.
Take care.
