I'd venture to say that they would be loud (IMG:style_emoticons/default/ohmy.gif)

those look like porsche factory megaphones welded to 914/4 flanges

iirc the p-megaphones have no damping at all (unlike supertrapps) so it would be like running without a muffler soundwise

I believe they used the megaphones instead of straight pipes because they have a 'velocity stack' effect

the main reason not to run a double exhaust like this on a /4 is because the firing sequence of the cilinders isn't equal left/right (unlike a /6) so you need a x-over between the left and right header/he

cheers,

jeroen
