Reply to "180 degree header question."

Though true for all exhausts, especially on 180s, it is remarkable how placement and even the direction the tail pipes point affect the sound. Tail pipes that point down toward the ground make a noticeable difference in audible noise level (softens) and placing the tail pipes apart in the two OE muffler pockets produces a different sound than a side by side arrangement exiting through the condenser grill. Of course affects are more pronounced standing behind the car or to an observer as you’re passing by and less noticeable for the driver from the cockpit……on the pipes at full song.

IMO, the center exit is definitely the best sound, more closely replicating a flat plane crank V8, but I still have a very difficult time looking at the back of my Pantera without OE appearing Ansa cans tucked in the original positions.

Best,
