From reading the posts on Mustang6g from both Gibson and Magnaflow..

Both are showing unturned 30rwhp gains, and both are showing 30lbs lighter than stock.

If a few more come back with gains of 20-30whp, I'll be willing to view it was legit.

We'll see

Edit: This quote was interesting..FordService has an active presence on that forum and likely would have disputed this..

"However we only released the dyno sheets with Ford's blessings."
