Gibson Single Axle-Back Exhaust for V6 Mustangs. Yay or Nay?

dab1990 · 09-28-2007

i have been trying to find the best axle back for the money and i was wondering if anyone has installed the Gibson axleback on their 4.0, they claim 10-15 hp and 30 ft/lbs tq but you know how those claims are...

any feedback or opinions would be a great help.

Sounds like BS to me. 5 hp maybe.

Also from the F150 forums, Gibson stuff lasts 5 years then you need to replace it.

I'm sticking with Pypes.
