Modified Mustangs & Fords (Marauder Exhaust Article)

if I read it correctly it was mostly tune...stock 234/254, with exhaust only 247/260, with tune 275/301, with tweaked tune 280/310. Exhaust only netted 13/6. Mine without exhaust mods is 275/303 so maybe about single digits (5/7) for exhaust on hp and torque. Maybe more difference as mine has 4.10s also.

Every car is such slightly different from the rest when it comes to how they react to mods.

I bet the car could of picked up more on the exhaust if the piping had been mandrel bent instead of the crush bent. It looks like the mid-pipe was a generic general one as well and not created with what kind of vehicle it would be going on as well.

I thought it was a pretty interesting article which is why I had to post it up.
 
Should have changed the over axle pipes too! I ran my OEMs for a long time and tolerated the noise. Big change when they were redone. And the welds look crappy any way!
