Default "Callaway" Performance Mufflers

I was searching through fleabay and came upon this, the owner states they're "Callaway performance mufflers", anyone have any info on these? Are they real? Any improvement over the factory mufflers?

I believe the Callaways simply came with the "Z51" freer-flowing exhaust. They then wrapped the tips together for a different look. Supposedly they are an improvement over the factory non-Z51 mufflers. I believe both tips flow vs the base mufflers?

Callaway did offer a "megaphone" exhaust on the turbo cars, but it had no actual mufflers. And they offered an exhaust system for the later SuperNatural cars, but I don't think they looked like the ones you pictured (and were apparently Super Turbo mufflers).

If the price is low, and you don't want a lot of extra noise, they may be worth the cash as a small improvement and a nice appearance.

They are factory dual outlet mufflers with the slip on Callaway tip. In 88 they warranted a 5hp rating increase if I recall.
