Corsa question? Crosover pipe?
 

I am looking for a 4" "stainless crossover tube" to connect the two exhaust that run from the riser to the transom. An old friend had them on his Baja a few years ago made by Corsa. They came on his boat from the factory. Reduced noise with through transom exhaust without having to get mufflers or silencers. Anybody know about this option? If so, where you we buy them cheep?

Did a little researce and looks like Corsa Quick & Quiet system model no. 12003 for a SBC. Their may have been two types: one with in-line mufflers and one without. We are looking for without.
