    Im assuming thats retuned results? Correct me if im wrong but if i had an EB which i don't and wouldn't, but if i did and bought this without a tune i wouldn't think there would be a lot of change? Just to clarify for some guys who may not understand. Just like my old 08 Mustang GT changing the diameter of the exhaust wont do a whole lot HP or TQ wise without an adjustment to the engine? Correct?

    I could be totally off my rocker so please correct me if im wrong!

    dyno graph is stock exhaust vs stock with 4 inch . aka no tune on that run for comparison purposes.

    a good 3 inch system will work on 5.0 or unless you want to try this 4 inch on the 5.0 ,, it would be different. :peace:

    Well if i were going to turbo it or S/C it i would probobly go with the larger 4" but i have no intentions of that on this truck so probly just stick with a 3" ill get with you closer to time when i can actually purchase my tuner and exhaust hopefully at the same time...thanks for the quick response though!
