I am new to trucks, but I am not new to modding vehicles. I have a full bolt on Mustang so I am not completely ignorant. My question is, I have noticed many of you recommend going with 2.25 exhaust piping instead of 2.5. Why is that. In the world of Stangs there is no way in hell anyone would run 2.25. Even with the 5.4 trucks it is being recommended. Why is this? On my Stang I have LT's, Off road 2.5 x-pipe, and dumped muffs. I am just trying to figure out why in the truck world 2.25 is being recommended as being better for power and not 2.5.
simple, 2.25" retains a good scavenging to move these 6,000lb bodies around, in a truck, low end power is important. In a 3800lb mustang, 2.5" is better because they can move at low end, and move even better in WOT range.
I really don't think it makes a huge difference unloaded, but I know 2.5" sounds better. Thus, Darren and I have 2.5", and they sound good! He is 100% right in theory. Even though the 5.4 makes tuns of torque, it is a 6000 pound truck. To someone pulling all the time, I would recommend 2.25" to maximize low end as well.
