i don't think it would. straight piping is actually pretty good for performance since there is still back pressure, but not much.

Slap a muffler on their for a farm tractor and theres potential it'll act like a potato just got stuck in the tail pipe...lol

Worth a shot though, I guess.

..not for a hemi...people running them may think or feel they're fast but NO really fast trucks are straight piping it.... I have a way of comparing it at the track since i have dual e cutouts... I consistently run almost .2 slower in the 1/4 when I open them up for runs...

This makes sense in a truck application if you think about it. Trucks are heave and require a lot of torque when compared to a lightweight, purpose built race car. A small amount of backpressure is beneficial for making low end torque whereas the open exhaust setup found on lighter cars is better for a top end charge.
